Somebody who loves heavy metal. Don't always have the "look". And it's not even necessary to listen to just the classic metal bands, you can listen to the subgenres. You just have to appreciate the genre as a whole.
OK, there's a lot of definitions that say that hot topic is "poser". Shopping at Hot Topic doesn't make you a poser. You just like their clothes. But if you shop there and think you're original, then you are a poser. They sell merch from some bands like Ramones, the Clash and Metallica, and it's pretty much the only store in the mall that sells band merch. But they are kind of expencive.
I just got an awesome pair of Converse and a Metallica shirt at Hot Topic.
