Ecchi

Ecchi (エッチ, etchi?, ) is an often used slang term in the Japanese language for erotic fantasy and sexual innuendoes. As an adjective it is used with the meaning of "dirty", "naughty", "frivolous"; as a verb (ecchi suru), with the meaning to do something dirty, naughty, frivolous or to sleep together; or as a noun, to describe someone that is seen as ecchi. It is a synonym for ero (from Eros) and does not have such a harsh meaning as hentai.
