Deluded teenagers (usually) who believe that by some how wearing all black and listening to rock music they become "individuals" while remaining blissfully unaware that they're just creating their own version of so called "chavs" and "trendies". They generally moan about being picked on and "labeled" while at the same time labeling others that don't conform to them.
They're no different from any other group effected by trend, punks, greebos, chavs, indie kids etc. It's all the same.
The Greebo's where moaning about how they are the only "individuals"
