Wearing your pants in such a way that you shit your pant for a month and no one would know (exept for the smell). The resulting bloated backside would be similar that of a ghetto booty or bubble.
Be a man pull up your pants! stop that saggin'

The way I've heard it is that sagging was a way for guys in prison to show that they had a gang behind them, or that they were in charge of a large group of inmates. It was like saying "here's my ass, go ahead, TRY to rape me."
That guy wears his pants around his knees cause he knows someone's always got his back.
