Keep in mind that's "attention whores", not "attention, whores". What a difference a comma can make.
The other day I heard an interesting theory. Someone said that women who wear skin tight, torn denim cut offs and florescent pink tube tops with the words "fuck me" printed in big, bold letters aren't at all responsible for attracting negative attention from the drunk, horny men they dangle themselves in front of. To that I say, well I suppose neither are the people who hose themselves down with Calvin Clein's new scent of sheep's blood cologne and go jogging in the woods only to get mauled and eaten by a cougar.
This really couldn't be any more simple. If you don't want attention, don't draw attention to yourself.
I don't care how much of a statement you want to make with your image, or if you're doing it all to be ironic; if you wear clown shoes, a stained tu-tu and a gimp mask, someone is likely going to take notice and give you some attention, and it won't be the positive kind. The only situation in which someone wouldn't make a unkind remark about your unusual attire is if they think that if you're damaged enough to wear that kind of shit out in public you're likely damaged enough to stab them with all your retard strength for pointing it out.
In a nutshell, the people who do these things are the same people who would do absurd and outrageous things in school to catch everyone's eye, only now they're all grown up and twice as dysfunctional.
