Holey Jeans

I'm confused by the trend of wearing torn jeans. Who in their right mind thinks it's cool to wear torn jeans? I mean it's just crazy. The reason that I'm on one of the computers in the library here on campus and there's this chick who has some really holey jeans. She may as well be wearing shorts for the amount of skin she's showing. I don't understand what would come over people to wear something like this? Seriously I do want an answer to this conundrum, so if you have a hypothesis or an actual reason for this please offer it up for me to ponder.
