In Japanese slang, dyke is rezu - clipped form of rezubian, from the English word “lesbian.” In formal Japanese, lesbian is doseiai no onna, literally ‘same-sex love woman’.
Atashi rezu yo! Dakara nan datte yu no?
So I’m a dyke! You got a problem with that?
They made a verb of rezu too:
Rezutta koto aru?
Have you ever done it with another woman?
A bull dyke is otoko-onna, literally ‘man-woman’.
Pejorative Japanese words for lesbian include onabe ‘pan’ (a play on the word okama for male gay, meaning ‘pot’), chidori ‘plover, wading bird’, itachi, ‘weasel’.
Diesel dyke is otachi. Derived from a term from Kabuki theater: tachiyaku, the sturdy, dynamic, masculine role.
Femmes are neko ‘cat’ and nenne ‘girly’.
Ano neko doko de hirotte kita no?
Where’d you pick that femme up?
Suzuko wa tsuyoi onna no koto suki ja nai no. Nenne ga suki nan da yo.
Suzuko’s not into butch women, she likes femmes.
69 is ainame, ‘mutual licking’.
Atashi-tachi mo nagai aida ainame shiatterun dakedo, saiko yo ne! Anta yattara ii no ni!
We’ve been going down on each other for years! It’s great, you should try it!
Kai is a poetic name for a woman’s vulva, literally meaning ‘shell’. Kaiawase, literally ‘meeting shells’, a Japanese game of putting shells together, is used for lesbian sex.
Chotto uwasa ni yoru to, aitsu no okusan tonari no onna to kaiawase shiteru rashii.
There are rumors that his wife’s bumping pussy with the woman next door.
Kono bideo suge kaiawase yatten no mieru ze!
This video shows some super cunt-grinding!
Another Japanese slang term for dyke is esu, the English letter S, which stands for “sister.” It seems a lot of Japanese slang is English-based.
Ano ko-tachi itsumo beta beta shiteru kara, kitto esu yo!
Those two girls are always all over each other, they must be lezzies!
Anta-tachi esu ja nai no?
You girls are gay, right?
