The act of farting and barfing at the same time. Often done after a night of drinking and eating bad enchiladas.
We stopped by Whiskey Pete's on the way back to California from Las Vegas. The buffet was so bad, I had to pull over on the side of the road and farf like a mofo.
Scenario: *you are at the salon. A lady with a ‘can I speak to the manager’ haircut storms toward you. Her name is most likely Karen or Susan.
Karen: Can I speak to the manager?!
Britney: No Karen, how dare you have the audacity to ask that? I have been busy farfing you selfish whore.
Karen: Go take your gastroenteritis infected arse elsewhere!
Britney: *farfs*
Karen: you farfing whore!
*Stage black out*
