it is true that sagging your pants relates to prison, that's exactly where it started. it was/is the way that male prisoners let each other know that they're willing to have sex without literally saying it aloud and risk feeling homosexual (which they are). I assume that with the many rappers in jail, when some of them finally got out they kept wearing their pants that way and impressionable idiots looked at them and thought that they were being fashionable so they followed them. some people will just follow anything that they see celebs doing.
Some people see it as a rebellious style or fashion. I consider it a low life fashion statement. It just tells everyone else, "I sag my pants, because I'm prairie dogging it and I have to drop a deuce."
Sagging your jeans and prison has no relation. ITs mainstrem fashion and it doent mean anything. Anyone can dress how they like. just becuase I guy wears pink, doesn't mean his gay. So just as a guy sags his jean, it doesn't MEAN anything. I sag my jeans a litlle. I think it look cool. I don't care what other people say, I do it because I thik its cool. Plus, a lot of girls llike it. A lot may say they dont, but many also do. I think its a little sexy actually..
