A genre of hentai in which the female character is immediately beaten by a strong male opponent and then fucked senseless. Popular among kissless virgins (or misogynists) who can't ask a girl out, or can't be fucked to go pursue a girl themselves.
Person 1: Favorite hentai genre?

Person 2: Instant Loss.

Person 1: You're fucking weird, man.
