Fat Punks?

So I was at an Irish Folk Punk concert last night. It was Irish, it was loud, and it was fun, and yes, there were Punks in the audience, as well as non-Punk people of practically all ages, from 15 to 55, I'd say, drinking Guinness out of cans and jumping around to the music.
As usual, while part of me was having fun, part of me was watching the people in the audience. And suddenly it hit me: I have never seen Punks, or Hippies for that matter, who were not thin or medium-well-built. All the Punks last night were thin, especially the two girls in torn fishnet stockings and a punk version of "Japanese Schoolgirl"-outfits. Are there no fat Punks or Hippies? And no, Mama Cass doesn't count.
I'm trying to conjure up the mental image of a small, rotund, mohawked, pierced Punk girl, and failing. Does looking like you've escaped from a Rubens picture automatically exclude you from that scene?
