When referring to someone as a faggot boi you are calling them trash at video games and they complaine about everything and most of the time they have aids or Ebola
Someone who talks trash on gay people even though they are gay and is hiding the fact that that are and has no life in the social world and most of them have diabetes, aids, Ebola, ect. They also masterbait to dog porn
No ordinary faggot, this faggot has exceptional abilities. Often found in forums or Call of Duty Multiplayer matches. Can be considered an antonym to Dragonborn, but instead of being an awesome dragon-slaying machine, the only thing he slays is fun. Often mocks you over the mic using retard noises, his high pitched voice (can be referred to as Faggot tongue), or really bad, juvenile "burns". If met IRL, he will appear as a normal child, but beware, he is born with the soul of the mightiest of faggots.
