They used it the other night on Family Guy, and since I knew what it meant, and my GF is rather, well, not into all that, she didn't understand how I spit my beer across the room when it was used.

PM me for a list of other terms you don't want to know like, Dirty Sanchez, Donkey Punch, and Dropping the kids off at the Pool.
