Why do teenagers and some young adults sag their pants?

everyone has their own style. some people, like yourself, prefer clothes that you feel fit you right. others prefer to sag their pants. i don't know why overweight people wear tight clothes, but if that's what they like, you can't tell them they can't dress like that. i agree with you that its pretty annoying when you have to look at people that dress like, in my opinion, complete idiots, but maybe people look at the way you dress and think the same thing?
