Punk is not easy to describe. It is people who want to be themselves and rebel against anything that is oppressing them. The music is such things like Caustic Christ and MC5. Not Green Day and Blink 182. Punk is not about your ex-girlfriend. That's called emo. Punk is about being an individual. But not even that anymore because the people classified as punk nowadays all look alike with they're highlighter colored hair, and fucked up clothes. And their fucking mohawks. Don't go for the cool look. Go for something that would make everyone stare. Not what every other punk wears.
