Not giving a fuck about what is cool or not cool, what is punk rock or not punk rock, or what is acceptable or what isn't. Plain and simple: Punk is a state of mind. If you think you're a punk then you are. Who gives a fuck.
Punk: "I listen to pop punk and I dont give a shit if its cool or not"
Douche: "Ughhh. Punks aren't allowed to like any bands that aren't in the Punk Rock Approved Hand Booklet that we all get when we up our mohawks for the first time. What are you doing, you trendy mall-shopping fuck? BLAH BLAH UP THE PUNX"
