Dude, why'd you hook up with that one girl who transferred?

I dunno. She said she was only back for the weekend, and that she didn't know if she'd ever be here again after that. I couldn't resist.

3.
Sexual manuever performed between a man and a woman while in the bathroom of a McDonald's Restaurant. While riding a female "doggie-style" the male begins to knukle punch his female counterpart on both sides of her rib cage. Though this act may sound painful it intended to provide an expression of love.
Linda told me not to cover her in Barbecue sauce while I was giving her the McRibb.

Nastiest item to ever grace McDonald's menu. A piece of dog turd molded into a rib shape, slathered in the poorest excuse for barbecue sauce ever conceived, and with pickles and onions on top.
