FAF = Fake Ass Fucker

when someone acts fake towards you, a two-faced ungenuine user who only talks to you if they want something

FAF

Noun/Adjective: Fine At First; context of seeing someone from far away, thinking they're good looking, and looking at them up close ruins the previous first impression.

May be used in context of a great first impression, but finding out a horrible personality.

Girl: Oh my gosh! That guy over there is so good looking.
Girl2: I agree!
*approaching guy*
Girl: Never mind. He's a FAF kind of guy.
