When you are at a party or a club and you need to fart so you move really quickly somewhere else and fart while you are moving, laying your odor everywhere but where you were.

Usually is really funny.
1 Hey man, I gotta fart, really badly.
2 Don't do it here, go crop dusting.
1 O shit, thats right.
