A bunch of kids who have been brainwashed into thinking that they are "helping the community" by going to hardcore shows and attacking anybody they don't see as worthy of their liking. They are the reason that straight edge gets a bad rap nowadays. They use their edge-ness to regard themselves higher than anybody who doesn't claim the coming of age trend. The irony of this is that more than 25% of the claimers actually abuse some chemical substance.
Basically they're a bunch of hypocritical idiots who really have nothing better to do with their lives.
"Did you hear about all those kids with down syndrome who started a gang?"
