I think somehow you have to have bigger "cojones" to go out on stage in stack heels and using a rhinestone encrusted axe than to have cut off combats, a wallet chain and a hamster stuck to your chin
It possibly also helps if you like your arguably-bigger 'cojones' being fondled by a large beardy German named Hans. :)
But on a serious note, I think it just takes a more outgoing personality, tbh. Some people just like drawing attention to themselves. In fact I think all people like this, it's just that some people do it through being outspoken opinionated gits on internet forums (the sad ****s like me), and some people do it by glamming up and gurning as they play on stage. The latter probably make for a better show (how else do you explain the absurd popularity of The Darkness?), but I can't change my personality, so there :) You'll just have to make do with Vociferators and obscene downtuned dirt :)
