the art or study of being a fag. calling one a fag is no different than gay. It actually has nothing to do with sexuality and only means essentially "lame" but with more emotion and resentment behind it. a perfect example is the south park episode "the f word" where fags were just obnoxiously annoying motor bikers that were causing an annoying level of noise pollution.
What kind of faggotry is this? Bikers can rev up their obnoxiously loud exhausts next to a library but a car with the same level of sound measured in dB is illegal. That is pure faggotry.
