Biff

When you think you are pushing out a fart but you actually slightly shit yourself, resulting in you having to throw out that 100 dollar Gucci underwear.

On a date with a hot chick.
Dave: "Oh shit I have to fart, but what if she hears? Fuck it."
*Juicy wet fart sound emerges*
Aileen: "What the fuck was that?"

Dave Biffed himself when on a date with a big booty hoe.
