When someone says a gay joke, something stupid, or something that deserves to be punished for. You also say beefneck while slapping the back part of their neck. Beefneck is a way to say that something is dumb; some people confess and put forward their necks and get hit, voluntarily.
Jimmy: Basketball is one of the dumbest sports ever.

John: Beefneck!!
