When one makes an unintentional posting error on Facebook. Derived from FACEbook + brainFART.
Man, I had a serious Facefart today--while posting to my gf's wall about how to properly execute a dirty sanchez, I accidentially posted to Mom's!

Slapping a bare arse cheek either side of someones face and letting rip. The victim is usually pretty pissed but also disorientated to give tou time to get away. The perfect crime.

A belch that has a reached stink, almost the smell of an anal fart. Usually occurs at bars when eating chicken wings and guzzling beer.
Matt belched at the bar when Joe replied "Gross! Face Fart! Go see a doctor, that isn't natural."
