When a player goes up for a dunk, completes it with a 2 handed stuff and then hangs on and pulls his legs up and straddles the player's head he just dunked on or near. It looks like a girl riding an out of control stallion. This happens in real NBA games as well as the NBA 2K games. Typically Brad Daugherty and Tyler Hansbrough can complete these with authority.
Guy 1: Damn bro, that was a fierce ass dunk! I can't believe you just dunked on me then rubbed your crotch in my face.

Guy 2: Actually, that's called a Cowgirl Dunk and that shit was rated TV-MA
