Faf

This basically means Fake Ass Friend. You know like Fake, like a bitch who always talks behind yo homies back? yeah, but this is a friend that is a bitch for talking behind yo back. it doesn't have to be a bad thing behind your back, it could be like talking to a friend that they have that hasn't been introduced to you or talking to your friend and they don't even tell you that they are talking to your friend. that is a FAF. a fake ass friend doing something you don't want them to be doin.
