Hot Cosby 

The act of drugging and then taking sexual advantage of a woman.

From South Park:

Cartman: Have you given her the ol' Hot Cosby yet?
Butters: No, we saw a movie and now we're going to the park.
Cartman: Butters, we don't have time for that. I told you, you have to cut to the chase with a Hot Cosby.
Butters: If I'm going to be with this girl, I don't want her someday thinking it was all super-rushed.
Cartman: Nobody cares about 40 years from now when she suddenly changes her mind, Butters. Time is of the essence; we're all going to die!
