Anime that contain a lot of sexual innuendo. The translation of this letter (Ecchi is the letter 'H' in Japanese) is pervert. Ecchi is about panties (pantsu) and bra/breast showing, situations with 'sudden nudity' and of course, subtle hints or sexual thoughts. Ecchi does not describe actual sex acts or show any intimate body parts except for bare breasts and buttocks. Ecchi is almost always used for humor.
