Hot Topic
A chain of mall stores with some cool shit in it... and some lame ass shit.
Shopping there does not make anyone any more of a punk or a poser then they already are. Why? Because it's a store, and a store in itself cannot be punk no matter what it sells.  Though many stupid kids feel the need to constantly say things like "Hot Topic is a poser store! Only posers shop there!", in order to make themselves feel more punk and hardcore about themselves. When they themselves are posers. 
Hot Topic is targeted twords the 16-25 age crowd.  I constantly hear people saying only teenie boppers shop there, though I've only once ever seen someone in there who looked under 17. 
The staff are in my experience very helpful and polite.
And it more often than not, smells good.

To sum up everything I just said:
Hot Topic is no more "punk" than Old Navy.
They have some cool stuff, and some lame crap just like every other store.
Dorks call it a poser store because they are insecure and want to feel better about themselves. And hope by saying that, others will think they are more hardcore.
