Down to double dick: When a girl is so desperate for cock that she’ll take two at once. It's a way to tease someone and call them a tramp or a cock-hungry ho.
You're D. T. D. D. again, just like last Friday.
Why are you D. T. D. D. when I’m still trying to get you?
You said you weren’t D. T. D. D. but you took both guys.
