The opposite of a cock blocker. Replaces "wing woman". Person who encourages hookups.
If you ever go out on the town and need a hook up take my best friend. She is the best cock tosser and can find you the hottest person in the room to go home with you.

A guy known for tossing his cock at every piece of pussy that walks through the door. Usually riddled with STD's, Cocktossers get laid so often that they will eventually turn gay or start raping sea animals.
Tommy's such a cocktosser, I called dibs on that asian chick that he's currently fucking in the bathroom.
