■ unplugged: Slang. adjective. behaving naturally and unself-consciously rather than boisterously, particularly towards a partner or friend. This sense of the word, heard among adolescents in the later 1990s and usually referring to male behaviour, is inspired by the use of the term to describe rock and pop musicians performing informal and relaxed acoustic sets as opposed to more contrived electrified stage shows.
