Lascivious behavior in the context of Sexual behavior

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.

The word ecchi has been adopted by western fans of Japanese media to describe works with sexual overtones. In western culture, it has come to be used to refer to softcore or playful sexuality, as distinct from the word hentai, which connotes perversion or fetishism. Works described as ecchi by the western fans do not show sexual intercourse or genitalia, but sexual themes are referenced. Ecchi themes are a type of fan service, and can be found in most comedy shōnen and seinen manga and harem anime.

An expurgation of a work, also known as a bowdlerization or fig-leafing, is a form of censorship that involves purging anything deemed noxious or offensive from an artistic work or other type of writing or media.

The term bowdlerization is often used in the context of the expurgation of lewd material from books. The term derives from Thomas Bowdler's 1818 edition of William Shakespeare's plays, which he reworked in ways that he felt were more suitable for women and children. He similarly edited Edward Gibbon's Decline and Fall of the Roman Empire. A less common term used in this context, also based on common editorial practice, is Ad usum Delphini, referring to a series of consciously censored classical works.

Fahsha or fahsh/Fuhsh (Arabic: فُحْش, الفاحشة, فاحشة) is an Arabic word, commonly means lewdness and indecency.
