Hentai Terms 101: Decoding Manga’s Naughty Terminology

Welcome to my blog post, where we delve into the world of Hentai terms. In this article, we’re going to look at the true meaning of "hentai," see how it’s been misinterpreted over time, and give you some useful fundamentals.

But that’s not nearly enough, right? We’ll also take a closer look at some intriguing or common hentai terms that you may come across in porn categories, clip descriptions, and even the cartoons themselves. And, maybe even an enticing tidbit about how sex-tech toys can be connected to the content! Are you ready? Let’s get started!

Hentai Terms – Japanese Origins & Evolution

What’s really interesting is that the word "hentai" is actually a complete misnomer (at least the way we use it in English). Most people associate it with "dirty cartoons." It’s an abbreviation of “hentai seiyoku” (変態性欲) which means “abnormal sexual desires.”

Japanese Origin:
In Japan, the word “hentai” (変態) translates to “pervert” or “perverted,” and it is a broader term that encompasses various sexual or deviant behaviors. So if you use the word in Japan, people will look at you funny. Originally, hentai referred to any form of sexually explicit or adult content. It wasn’t just manga or anime, but all forms of sexual perversion (media or otherwise). Hentai could also include explicit written material or adult-themed artwork.

Introduction to the Western World:
As anime and manga gained popularity worldwide, “hentai” became synonymous with animated pornography, particularly in Western countries. This shift in meaning occurred due to cultural differences, interpretations, and the specific interests of Western audiences.

Now, What You’ve Been Waiting For … Hentai Terms!

Ahegao (アヘ顔) – The face you make during orgasm. Specifically flushed cheeks, eyes rolled up, mouth open, and tongue sticking out because it’s so good.

Bakunyū (爆乳) – Really big breasts, so big that it can only be achieved through surgery. The literal translation is “exploding breasts”. The next stage would be “chōnyū” where the size is impossible.

Bishoujo (美少女) – Means “pretty girl”. This usually translates to young, attractive, anime-style females within Japanese media. This is often referred to in bishoujo-style figures or bishoujo games within the visual novel and galge genre.

Bishōnen (美少年) – Means “beautiful boy”, sometimes abbreviated to “bishie”. It’s a Japanese aesthetic concept of the ideally beautiful young man: androgynous, effeminate, or gender-ambiguous.

Bukkake (ぶっかけ) – Yeah, this act of covering someone in semen isn’t just for live-action porn. Where do you think the word came from anyway?

Chinran (産卵) – A fetish where an alien or monster impregnates a woman and she bears the offspring, usually in the form of eggs – hence the translation “egg laying”. A company called “Primal Hardwere” actually makes dildos (called Ovipositors) that mimic this fetish by inserting gelatin-like eggs through a hole in the toy.

Diipu kisu (デイープキス) – A French kiss.

Dojikko (ドジっ子) – A cute girl who is usually quite clumsy. This often causes harm to others.

Doujinshi (同人誌) – Also called “doujin” is self-published work that can be anything from manga, magazines, novels, and more. It’s also used for self-published hentai fanfiction.

Ecchi (エッチ) – When referring to porn it means “softcore” and not dirty enough to be considered true hentai. Sometimes called “H-manga.”

Eroge (エロゲン) – Comes from the words “erotic games” and is used to describe sexual video games of varying degrees of spiciness. These can be dating sims, visual novels, or even combat or management games. But there’s always sex involved and often the look is very manga.

Futanari (二形 / ふたなり) – Characters with both sets of genitalia (including breasts). “Double form” = Hermaphrodites.

Galge (ギャルゲー) – A Japanese adoption of 'gal' (girl) game. Galge is a genre of visual novel and dating sim that focuses on developing a romantic relationship with a girl among a cast of several attractive, anime-style girls.

Gokkun (ゴックン) – The onomatopoeic sound of swallowing, specifically semen.

Hadaka (裸) – Where characters perform household chores in just one piece of clothing – like a skimpy apron or ribbon.

Iryō fechi (医療フェチ) – An all-encompassing term for various medical fetishes.

Joō-sama (女王様) – A Dominatrix. Just like in English, it’s for females only.

Kuikomi (食い込み) – “Flossing” by pulling a girl’s panties or tights and moving them back and forth to stimulate her.

Rūzu Sokkusu (ルーズソックス) – “Loose socks”. Many words in Japanese are a verbal adaptation of their English counterparts. In this case, it means the schoolgirl uniform socks that don’t quite stay up.

Meganekko (めがねっ子) – A genre where a girl wearing glasses is more attractive. Often shy, bookish, or submissive.

Moe (萌え) – Slang for the feeling of affection or adoration towards fictional anime characters, particularly those portrayed in a sexually innocent or cute manner. It emphasizes an emotional connection or attraction, rather than explicit sexual content (but not always).

Nikutai kaizō (肉体改造) – Changing the body through science or surgery, sometimes to have extra body parts likes breasts, etc. (think Total Recall and the three-boobed woman).

Oshouji (お書字) – Where a dominant writes calligraphy characters on the sub’s body.

Potchari (ぽっちゃり) – A broad term for a fetish towards larger women.

Ribāshiburu (リバーシブル) – A verbal adaptation of “reversible” which is a gender-neutral term for “switch” (between dominant and submissive).

Shokushu (触手) – Good, old-fashioned tentacle porn.

Tamakeri (玉蹴り) – Kicking someone in the balls, whether masochistic or sadistic.

Uke (受け / 請け / 承け) – The bottom or receiver in a gay relationship.

Bācharu Dēto (バアチャルデート) – “Virtual date”, similar to erotic video games (eroge) where a client goes on a video date.

Wakige Fechi (腋毛フェチ) – Underarm hair fetish.

Yagai (野外) – Sexual acts outside, but not always intercourse.

Zenra (全裸) – Doing activities completely naked (one step beyond Hadaka – one piece of clothing).

Hentai Terms for Breast Size

Other than our standard cup measurements, idioms, and standard adjectives such as big or tiny, we don’t have much in the way of describing breast sizes (not including slang). But you can bet there is in Japanese Hentai terms.

Munyū / petanko / pechapai = flat chested

Chippai / binyū = A cup

Hinnyū = A-B cup

Futsū = ordinary breast size

Kyonyū = naturally large

Bakunyū = really big, only through alteration or surgery

Chōnyū = impossibly big (like the last 5 images LOL)
