Ecchi

Ecchi (エッチ, etchi, pronounced [et.tɕi]) is a slang term in the Japanese language for playfully sexual actions. As an adjective, it is used with the meaning of "sexy", "dirty" or "naughty"; as a verb, ecchi suru (エッチする or Ｈする) means "to have sex", and as a noun, it is used to describe someone of lascivious behavior. It is softer than the Japanese word ero (エロ from Eros or "erotic"), and does not imply perversion in the way hentai does.
