Punk - These people wear tight jeans and flambouyant clothing. They like to skateboard, some get into mischief, and they do unusual things. They listen to punk music(ex: Avril Lavigne).
As a 'Punk' I really REALLY have to disagree with your example of Avril Lavingne.

She makes pop records. End of story.

*shakes head sadly*

Maybe I'll stretch to punk-ultra-lite to discribe her.
