Here's how it worked,
metrosexual came along and suddenly being a straight
guy who could be easily mistaken as being gay was cool, and like anything that becomes cool you always have the problem of....posers.....and there were alot of them, not to metion all the real metros who were pissed off at the posers. Thus
uber sexual came along to further distinguish the real metros and the hardline posers from the less vigilant posers and the metros who didnt care bc they didint have to tell everyone they are metro.
