Hot Topic is a store for kids interested in "punk" and/or that are "goth." These kids supposedly wear Hot Topic clothes because they "don't want to dress like everybody else at school." Of course, there are many kids who wear Hot Topic clothes, and they all end up dressed alike.
99% of the clothes at Hot Topic are black. Also, the clothes are covered with safety pins and the like. Kind of creepy if you ask me.
Also, all the people that work at the store just look downright creepy with their dyed red hair and their nose rings.
