In basketball, when an offensive player is poised to score emphatically on the defense, except at the last moment his shot, usually an easy dunk or layup, is blocked with an equal or greater amount of emphasis. The highlight then becomes the embarrassment of the offensive player not making his shot. See also "Posterized".
