F3

F3 is originated from a 2D Online game called Maple Story. In game players would press the F3 button to change the face of their character to a sarcastic face. The face can be used to annoy players after they did or say something stupid. Some players choose to use the term "F3" outside of game such as in everyday speech or Messenger.

Messenger:
Friend: I just failed my maths test.
Maple Player: LOL! F3
Friend: huh?
Maple Player: F3

In Game:
Player 1: Dude, let me in your party.
Player 2: No F3
Player 1: WTF man why are you so cocky online?

Player 1: Just wait 'till i see you tonight.
Player 2: ok F3.

F3

F3 is an acronym for FFF which in turn is an acronym for: "Fat Fucking Failure". Some say just "Fail" instead of the full "Failure". Used in internet slang to say that an event is bound to be/or is a failure i.e. not as good as the organizer intended.
