"In music, punk remains what the critic Frank Kogan calls a “Superword”—a term whose main purpose is for people to fight over what it should mean, using it as a “flag in a bloody game of Capture the Flag.” It’s a concept like “freedom” or “the one true Church” or “real Americans”: to invoke it is to advance a vision of what it entails, and duke it out with competing visions. (Saying that real punk only lasted 100 days is a terrific example of how Superwords work.) In the 37 years since a good mass of people decided “punk” was a flag worth waving, we’ve seen countless versions of it, most at odds with one another. There’s punk that’s dissolute and nihilist, and punk that’s earnest and abstemious; punk as attitude, as economic model, as ideology, and as an ordinary subgenre of music; punk that’s funny and punk that’s humorless; Fascist punk and anti-Fascist punk; punk that sounds like 1977 and punk that can’t imagine repeating the past; you name it. If there’s any reason the stuff’s stayed in the bloodstream of rock, it’s that the idea is flexible enough to put anything into it, take anything out, and feel like you’re fighting the good fight—the word itself is mostly just permission to get into the ring."
