Used to describe the action you take when you are presented with losers. Rather than confront them, it's way to just let them know that you are displeased with their behavior.
I can also be used for any version of the verb "to fart"
Farted On Losers
Fart On Losers
Fartin' on Losers
Farts on Losers
You: FOL, NBD.
Friend: Whatta you wanna do tonight?
