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!

Beef Necklace 

Somewhat similiar to the pearl necklace, only semen is replaced by a log of shit in this variant.

My girlfriend wanted me to buy her a pearl necklace for her birthday. But instead I gave my brother Rob a beef necklace that night.

Jenny tried to give me a beef necklace, but only succeeded in shitting in my mouth.

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)
