Good Point UB,

The difference is that these teen guys just let the pants sag low. They keep their boxer shorts high.

In prison, the punk look is to have no underwear showing. What you see is the prison jeans worn as low as they'll go with "reverse cleavage" or "plumber's butt" showing.

At the prison's I've worked it didn't mean the guy was taken, it meant he was available - for a price. Sort of like a street hooker on the prison yard.

Hey, maybe somewhere, some way, some state dept. of corrections will issue kilts as standard issue prison wear instead of jeans....naaa, too much freedom....
