When a boy/man, walks to a urinal, begins to urinate and waves his dick around the surface of the urinal as if to hit imaginary targets inside of the urinal. It can be quite entertaining to watch them spaz out while pissing.
Boy 1- "Did you see that guy in the bathroom?? WTF was he doing wavin' his dick around like that??"
Boy 2- "I dont know dude, maybe he was shootin' helicopters."
