Basketball slang
This article is about dramatic athletic performance on offense. For the graphics technique, see Posterization.
Posterized is North American slang, derived from an action in the game of basketball in which the offensive player performs a slam dunk over a defending player, in a play that is spectacular and athletic enough to warrant reproduction in a printed poster. The term was originated from Julius Erving, whose high-flying style of play inspired the term. Posterized is also used infrequently to describe similar events in other sports, and it has made its way into business writing.
