When you and your buddy are fucking a girl, she's blowing one and taking one, then on the count of 3 you and your busy yell "SCOOBY DOOBY DICK SWAP!" And you switch places and make her ask for Scooby snacks at the end.
Hey Paul, wanna go over to Jenny's later and give her the good old Scooby Dooby Dick Swap?
