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.
