1. FAT ASS FINGERS: a name given to one because of their
hilariously oversized, sausage-like fingers
2. Acting in a way that just fucks up the situation.
Extremely popular in the Buffalo suburbs.
Fafs are often seen in pictures giving the shocker.
Note: despite the fingers, fafs still manage
to get laid.
"Dude, get your fafs out of my drink"
As the faf drives by a hot girls house, he points
out the window with the fafs yelling, 'yo, is that her house' As this happens the girl walks outside thus
embarrassing everyone
in the car. He has committed a faf, or we say he faf'd it up.
Also common is the faf of the night. This occurs when one drops a beer, soils themself, gets their fake id taken or any other fuck up.
