1. A person who believes they're hot shit
2. One who brags about stuff no one else cares about
3. Someone who talks shit about other people behind their back because they're an incompetent and insecure douche cock
Person 1: Told you he was a fag. Why did you hang out with him? I'm so much better than that fag.
(Person 1 is insecure about actually being a fag and trying to divert attention from their fagginess by calling other people fags and saying he is better.)
Person 2: Shut up dick fence! Quit being such a fag you gay homo douchey douche cock.
