What highschool stereotype/group is this?

so im just kind of wandering they come in with band tees or just plain t-shirts with a design on it, along with cargo pants, or jeans not skinny just normal, with beanie hats or aviator sungles. i see them hanging out at the record store or coffee shop a lot and they listen to anything from we came as romans to pink floyd to rise against, but mostly keep it in the rock/metalcore area. they play rock instruments(guitar, b,drums). they arent really unpopular because theyve all had girlfriends and i sometimes see them at parties, aside from that, when they are in public(not a music store) they tend to get kicked out for rowdy behavior. any ideas?
