FAMF 

N. meaning Fake Ass Mother Fucker

or

V. (when used with GA) a process, where by disrespecting someone in a certain way using very specific steps, is used to call someone out on their being a "Fake Ass Mother Fucker".
(Similiar to the "you're stuck wtih it" game, but more covert and fun. Also used competitivly to trick friends.)

Steps to complete a (GA)FAMF:
1) Hone in on your target.

2) Say something to the target that catches them off guard and makes them say, "What?"
(Helpful Hint: A good trick is to mumble something semi-incoherent to them while they're in another conversation, or spout a fast string of non-related words in the form of a question. The idea is to be as creative as you can.)

3) Wait for the target to say, "What?"
(READ: Only the word "What?" works. If they say something like "huh?", or ignore you, you have failed your mission.)

4) Quickly shout "GA FAMF!"
(The GA stands for "Gotcha!". If you yell FAMF without the GA, it doesn't count, and you lose. If this happens, and the other person knows the rules of a FAMF, this is their time to rebutt with their own GAFAMF.)

FAMFing can also work with text messaging and instant messaging.

Sally: ...and I couldn't believe Bobby said that, especially after buying his new SUV.

Veronica (your target): I KNOW! And like, I had just gotten my nails done on-

You: AreVeronicaTheAntZooThinksICan?

Veronica: What?

You: GA FAMF bitch!
