When a man farts (blows air) out of his penis. Like a quief, only its when a guy does it. There is no scientific proof that this can happen.. but it is fun to say.
What you say when you knowthe shot you're taking (in a game of basketball) is gonna be so wet, it sounds like a guy biting a apple. (Wet meaning "all net")
Paulo: Who wants to get shit on?
Stru: *goes and D's paulo so Stru puts his hand in his face as Paulo takes the shot*
Shot: *quoof*
Paulo: SHIT ON NIGGAS DOT COM!!
