D.T.D.D.
Down to double dick: When a girl is so eager for two guys at once that she's basically a cock-eating monster. It's a way to roast someone and say they're a total tramp.
You're D. T. D. D. and I’m still waiting for my turn.
You called me D. T. D. D. but I only took one cock.
You said you were D. T. D. D. and then you ran away.
