How I described pop punk kids in recent e-mail:

"The pop punk kids are so funny. It's like an identity crisis...am I a trendy prep, or a rebel punk? clean? dirty? They just end up looking stupid."

Pop punk is punk forking mainstream. Some pop punk is really good, but most of it sounds like watered down punk rock. Not to mention most startup pop punk bands suck, and are completely unoriginal. They're all about trying to look cool and act punk, rather than startup punk bands who tend to be in it for the music and the scene.

Fun Size is the only pop punk band that comes to mind who I respect, I'm sure there are a few others though...
