Doobie dick is a famous party which involves a male inserting a doobie(joint) into his penis and proceeding to wave it about trying to burn fellow party goers.
Jim: James did the doobie dick last night!!
David: Oh my god, seriously?
Jim: He ended up burning some girls forehead.

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.
