Actually, it derives from the fact that prisoners don't get belts so they can't commit suicide by hanging. So they're pants sag. Then when they get out, they continue with that "style." Then the kids who've never been to prison started wearing their pants that way because it was "cool." Some of the elaborately pin their pants in place with safety pins to maximize the sag.
The other contributor to the look are skateboarders who like a low crotch to keep the board from whackin' the jewels when they kick the board up.
