Hentai Terminology 101 (EXTREMELY NSFW)

Hi all! This is a podcast adaptation of a panel we've been giving for the past 2 years about the kinds of words you encounter when reading hentai (and much more). As you're listening to the podcast, be sure to check out this handy-dandy guide we've put together with visual representations of what we're talking about in each section. All of the images used here are sourced directly from pixiv.net, and you can mouse over every one to see what it's illustrating, and click on them to go to the page/artist it was sourced from (which we highly suggest you do).

In case this was not abundantly clear in the title, the entirety of this post is VERY NSFW and contains some pretty graphic stuff. Turn back now if you aren't into that.

That being said, let's get going!


Hentai - 変態

Short for hentai seiyoku, it originally meant any unusual (“hen”) perversion. The term was popularized in Japanese psych journals in the early 1900s and then co-opted by perverse magazine authors. It’s important to note that hentai does not describe a genre in Japanese like it does in English. In Japan, pornorgraphy is normally donated as eromanga, or adult manga.


Ahegao - アヘ顔

"O-Face"

Ahegao is the slang term for "O-face", or the face someone makes during orgasm. It's usually characterized by crossed eyes and an open mouth/lolling tongue, with associated bodily fluids running down the face for full effect. Etymology-wise, the アヘ is read “a-he”, and the 顔 is the common kanji for face, read “gao”. Put them together, and you can see where we're going with this. Often seen in conjunction with the ahegao is the ダブルピース, or double peace.

BONUS! Zettai Ryouiki - 絶対領域

"Absolute Territory"

This is almost assuredly one you've heard before. It translates to "Absolute Territory", and refers to the area of skin between the bottom of the skirt and the top of kneesocks/stockings. It comes from the term Zettai Kyoufu Ryouiki, which originates from everyone's favorite anime Neon Genesis Evangelion, originally referring to the AT Field or "Absolute Terror" force-field that the Angels and Evangelion units produce.

Nakadashi - 中出し

"Creampie"

Sotodashi - 外出し

"Pulling Out"

These two terms end with the same phrase: Dashi (出し), which is made of the kanji 出 (out/going out) and し. The Naka (中) and Soto (外) part make the rest self explanatory: naka means inside and soto means outside. So, it follows that nakadashi is finishing inside and sotodashi is finishing outside! As far as encountering these terms in the wild goes nakadashi is incredibly common, but outside of picking your choice in an eroge you won't hear sotodashi too often.

Bukkake - ぶっかけ

"Smothered and Covered"

Another term you've probably heard before. Bukkake comes from the verb bukkakeru, which means to splash or cover something with a liquid. The use of it in a hentai context is pretty self-explanatory, but its use isn't limited to just sex: bukkake udon is a popular kind of udon dish in Japan, with a bunch of stuff piled on top of the noodles.

Body Parts!

Oshiri/Ketsu - お尻/ケツ

"Butt/Ass"

The full moon. In reference to the butt, the descending order of polite to vulgar terms is oshiri->shiri->ketsu.

Futomomo - 太もも

"Thighs"

The thighs, and also an incredibly fun thing to say. Coming from futo (太) meaning fat or plump, and momo (もも) meaning peach. So it follows that thighs are a "fat peach".

 Oshiri/Ketsu

Manko - まんこ

"Vagina/Pussy"

The vagina or pussy (almost always the latter in translation). Manko is an informal, vulgar slang term and would never be used officially or in a medical sense.

Chinko - ちんこ

"Penis/Dick"

Another vulgar slang term, this time in reference to the dick or penis. The dick can also be called a million other things, most hilariously musuko 息子 (son). If you've ever been watching Gintama and heard bleeped words, it's probably been this or manko.

Mae Kara Mieru Oshiri - 前から見えるお尻

"Ass You Can See From the Front"

The title says it all! This is when you can see the butt cheeks from looking on from the front. The visual aid will be your best friend in this case.

Oppai - おっぱい

"The Tiddy"

This is a big one: the tiddy. They're usually referred to by "oppai" which is probably a term you've heard before, but you can also say "mune" to refer more to the chest itself or just be more reserved. Just like every language, there’s a ton of ways to describe honkers in Japan. They’re all spelled with ☓乳, where ☓ is a kanji describing their size and 乳 is for boob. You'll see some examples in the next section.

Hinnyuu - 貧乳

Small or flat. Can also be called pettanko.

Kyonyuu - 巨乳

Big. The kyo is the same one as in Shingeki no Kyojin.

Bakunyuu - 爆乳

Huge! Literally explosive breasts. Baku could be from bakuhatsu for “explosion” or bakudan for “bomb”.

 Hinnyuu

BONUS! Shitachichi - したちち

"Underboob"

Situations in which you can see the underside of the breast. Shita is the word for "under" and chichi is another slang term for boobs, literally "titty".

Clothing!

Seifuku - 制服

"Sailor Uniform"

Sei is short for seira or "sailor", and fuku is a generic and common word for clothes. Originally seifuku referred to the stereotypical sailor school uniform, but can now refer to just about any uniform.

Mizugi/Sukumizu - 水着

"Bathing Suit/School Swimsuit"

Mizugi is the generic word for swimsuit (one piece, bikini etc), while sukumizu refers specifically to the standard school-issue swimsuit you often see in media set in high school or middle school.

Megane - 眼鏡

"Glasses"

Mega is the word for "eyes"! This one kind of explains itself.

Shimapan - シマパン

"Striped Panties"

Shima is the word for stripes, and pan is short for pantsu or "panties". Thus, striped panties!

BONUS! Hiyake Ato - 日焼け後

"Tanlines"

This translates literally to "after sunburn".

DOUBLE BONUS! - Mecosuji - メコスジ

"Cameltoe"

Meco is another slang term for vagina, and suji is specifically a "line of fiber".

Onani - オナニー

"Masturbation"

 We're certain that Japan has the best word for masturbation out of all the languages. Onani comes from the Book of Genesis chapter 38, referring to Onan, the second son of Judah. Onan was slain by god for pulling out too early and spilling his seed on the ground. Early Jewish and Christian views interpreted the passage to mean that masturbating is bad.

And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother. And the thing which he did displeased the LORD: wherefore he slew him also. - Genesis 38:9-10

Acts!

Ashikoki - 足コキ

"Footjob"

Tekoki - 手コキ

"Handjob"

These two work the same way as nakadashi and sotodashi. 足 (ashi) is the kanji for foot or leg, and 手 (te) is the kanji for hand.

Oshikko - オシッコ

"Watersports"

This is a fairly common phrase outside of hentai mostly because it's seen as somewhat of a childish term for peeing, usually what kids would say to their parents, i.e. "I need to wee-wee". The term omorashi is another in this specific category and refers to the act of having an "accident" or wetting oneself. It can also refer to the specific fetish subculture of liking to either wet yourself or watch someone wetting themselves.

Paizuri - パイズリ

"Titfuck"

Pai is the shortened version of oppai, or breasts, and zuri means to rub against or between. Paizuri is technically a part of irrumatio.

Irrumatio - イラマチオ

"Anything Else"

Irrumatio comes from the same latin term, and means thrusting the penis between anything that isn't boobs. Usually means between the thighs or through the armpit, though can also refer to stuff like facefucking.

Traits, Genres and Fetishes!

Osananajimi - 幼なじみ

"Childhood Friend"

Inseki - インセキ

"In-Laws"

Any non-blood related family, usually through marriage or adoption.

Gyaru - ギャル

From English "gal", and it has a ton of different meanings. A lot of people think the standard ganguro/kogal stereotype first, but a gyaru is usually a girl who doesn't subscribe to the usual definition of Japanese attractiveness. This can include dyed hair, glitzy fingernails, a modified seifuku, or an unbuttoned top.

Netorare - 寝取られ

"Cuckolding"

Netorare is almost always abbreviated as NTR. Cuckolding is a term taken from the cuckoo bird and its mating habits, where the dominant male will force a less dominant male to look after its female's eggs. The human version isn't much different, where a more alpha dude has sex with a less strong dude's girl as an act of dominance, sometimes even in front of him. This is an especially difficult concept to illustrate simply, so if our example doesn't do it for you just search the NTR tag on Fakku and you'll get an eyeful.

Loli - ロリ

"Young-looking Girl"

Loli comes from the novel Lolita by Russian author Vladimir Nobokov. Refers to a "young-looking girls", and this is key because it's a sort-of trope that loli characters can either be their age or thousands of years old, but look the same.

Shota - ショタ

"Young-looking Boy"

This is the shortened version of the word shotacon, which itself is short for shotaro complex describing an attraction to young boys. It's a reference to Shotaro Kaneda, protagonist of a famous 1950s manga called Tetsujin 28-go.

These are both fairly controversial subjects in 2018 and can exist within a severely grey moral area, but it should be noted that they're both technically legal in the US as long as they're not based on actual kids, and we figure since this is supposed to be as academic a presentation as possible, if you're going to be looking up hentai online it's better to be knowledgeable about this stuff than not.

JC - 女子中学生

"Middle School Girl"

Short for joshichuugakusei, literally "female middle school".

JK - 女子高生

"High School Girl"

Short for joshikousei, literally "female high school".

Both of these are used as hentai tags online all the time, and below you'll find the covers of two well-known magazines that cater to JC and JK specifically, Juicy and Comic Koh. You'll notice that each of their names are representative of the type of content they serve up- Juicy sounds like JC in Japanese, and Koh is short for the kousei in joshikousei.

Yaoi - やおい

"Boys' Love"

This is another pretty common term but not many people in the west know that Yaoi is an acronym for yama nashi, ochi nashi, imi nashi which means "no climax, no point, no meaning". "Yaoi" has kind of fallen off as the given name for this genre in the west mostly because of the unfortunately negative (and homophobic/anti-women) connotations attached to it, so most of the cool kids are calling it "boys' love" or "BL" for short nowadays.

Yuri - 百合

"Girls' Love"

Yuri comes from the Japanese word for the white lily, which in the Japanese language of flowers symbolizes purity and chastity. Unlike the whole "yaoi/BL" name debate, Yuri is the accepted and most widely used name for this and you'll almost never hear "girls' love" or "GL".

Some BL Terms

Seme - 攻め

"Dom"

Uke - 受け

"Sub"

Riba - リバ

"Switch"

If you're going to be reading BL, these are terms you absolutely need to know. Seme comes from the verb semeru which means to attack, and Uke comes from the verb ukeru which means to receive. These are sometimes translated as "top" and "bottom" but we prefer the more professional "dom" and "sub" for "dominant" and "submissive" in modern western fetish parlance. Riba comes from the English word reversible and refers to a "switch", or a character that can be both seme and uke. Usually the trope is that the Riba is a seme with one character and an uke with another. It's important to note that seme and uke are used exclusively when referring to BL in Japanese and would almost never be used to refer to roles within an actual gay couple, but we'll get to those terms in just a second.

Tachi - タチ

Neko - ネコ

Tachi and Neko are similar if not essentially interchangeable with seme and uke, with some key differences. They can be used both in reference to a real-life gay relationship and also to one in BL or geikomi (gay comics, a term you'll learn in the next section). Originally these two terms started as parlance in the Japanese lesbian community, which is why they're often associates with yuri as well. Tachi and Neko can also sometimes be used to describe more the emotional aspects of each role than the physical positions. As far as etymology goes, it's a little less clear than Seme and Uke. For Tachi, the best guess is the "tachi-yaku", the leading actor in a kabuki play.  Neko is most likely named after the Japanese word for cat - representing the shy, timid side of cats, anyway.


Bara - 薔薇

"Mens' Love"

Bara literally means "rose" in Japanese (not unlike how yuri refers to the lily) and is a broad term that describe gay porn made by gay men, for gay men (as opposed to yaoi/BL, which is usually made for women by women). It arose in post-war Japan in the 1950s from magazines like Barazoku (literally "rose tribe") and ADONIS, and was also a popular slang term for gay men during that period. Bara manga can also be called geikomi, or "gay comics". Bara is often much more realistic and commentative than any other kind of hentai or eromanga, commenting on social issues facing gay men in Japan. Nowadays bara features big, burly men with notable muscles and oftentimes body hair.

Gengoroh Tagame - 田亀 源五郎

This is more of an aside than anything, but we absolutely couldn't talk about bara without mentioning its most prolific author and artist, Gengoroh Tagame. Tagame is an openly gay mangaka who is easily the most influential bara, geikomi and BDSM artist from modern Japan and one of the most influential in the world. He's known for a 30+ year career drawing gay erotica but has more recently received acclaim for his all-ages series My Brother's Husband and Our Colors. Basically, if Osamu Tezuka is often considered the "manga no kami-sama" or "god of manga", then Tagame is the "geikomi no kami-sama" or "god of gay comics".

Josou / Otokonoko - 女装 / 男の娘

Josou is the act of crossdressing. In spoken Japanese Otokonoko means boy, and it is normally written as 男の子, with the 子 being ‘son’. When referring to a crossdressing boy it’s written 男の娘, using 娘 for daughter, but pronounced the same. Otokonoko (in the crossdressing context) is normally translated as "trap", and there's a lot of baggage that comes with that term despite the fact that it is an accurate translation. The fact is, "otokonoko" and "trap" both have culturally negative connotations and thus can be considered real, hurtful slurs by members of the queer and trans communities. Knowing this, it's ultimately up to each individual to determine what they want to engage with in this realm, but you can rest assured "trap" is not a word you'll ever hear us using, and again if you're going to be searching out and engaging with the hentai community online this is something everyone should be aware of.

Kemonomimi - 獣耳

"Beast Ears"

Kemono is the word for beast and mimi is the word for ears! This one is supremely simple, and also applies to everything regardless of gender. Fox, cat, wolf, bear boys and girls, if it's a beast and it's got ears, they can be put on a person and it can fall under this category.

BONUS! Kemohomo - ケモホモ

"Gay Furry Stuff"

This is another one that's almost entirely self-explanatory. Kemo is obviously from kemono and homo is taken from the English word "homosexual", denoting the gay stuff. You'll find mostly bara-centric art in this tag online.

 Kemohomo

Futanari - ふたなり

"Hermaphroditism"

The literal translation for futanari is "dual form", meaning hermaphroditism or a character that has both sets of genitalia.This is the true definition of futanari or "futa" in Japan however recently and especially in the west, futa has become associated with women who have or somehow grow or receive dicks without the necessary requirement of having both sets of privates. Also, for reasons that are beyond us, the dicks are almost always HUGE.

FINAL BONUS! Real-life Trends

For our final bonus section, let's take a look at some memes and trends that started in the real world and made their way into hentai artist communities online.

Jigadori - 自画撮り

"Selfie"

Jiga is self-portrait, dori is the verb to take (a photograph). This one is interesting because it’s the opposite the normal trend - セルフィー (serufi) is used normally even though it’s an English loanword, whereas the “proper” Japanese jigadori is used only for erotic means.

The Tawawa Challenge - たわわチャレンジ

This is an internet phenomenon inspired by an image posted by Tawawa on Monday creator Kiseki Himura on twitter, in which the main character of his image series is balancing her phone on her boobs. The challenge started first in real life, and then spread to 2D.

Virgin Killer Sweater - 童貞を殺すセーター

Literally translated as "The Sweater that Kills Virgins", it was originally popularized in a series of images circulated on Japanese twitter in 2016 labeled "Clothes that Kill Virgins". The trend quickly spread to Chinese social media and exploded from there, eventually making its way into 2D art like all these things eventually do. Much like Rule 34, there's a virgin killer sweater rule out there that says if you have a favorite character, there's art of them in a virgin killer sweater out there somewhere.
