Hentai

A Japanese word denoting unfavorable (or favorable, depending on context and circumstances) sexual connotations.
A loose English translation would correspond to words like "perverse."
Contrary to popular belief (and to its usage in America), when used as a noun, this word denotes a person who fits this description and nothing more.

I was accosted by a hentai on the way home from work.
