a very easy girl who is willing to perform sexual acts with nearly any individual. Usually at large parties, within groups of friends. She acknowledges the fact that she is the 'tossup' and wears the name proudly. She is aware she is there for sexual satisfaction.
In AZ's song "Tossup", "...you know the kind of girl the ones we call up, never knowin em by the name so we call em tossups, hold up, the kind of girl that you don't fuck up in the bed, that's quick to give you head and never ask you for no bread, every nigga down here know her, she's down to do what niggas want, we hit it from the back she even let you put it in the throat..."
