Beefneck 

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!!

(Slaps back of neck)

beef neck 

when you playfully *slap* the back of someone's neck, usually after they make a dumb or obvious statement. saying "BEEF NECK!" is optional while administering the *slap*.

After Bobbi asked me where her keys were, I pointed out they were right in front of her on her desk, and then gave her a BEEF NECK!
