prison sag

Pants that are worn below the waste line, exposing underware. This origin is prison. When nigger inmates wore pants that were sagging in order to have gay sex and not get caught. The idea of sagging made it easier for nigger inmates to have sex and pull their pants up before the prison guards approached.

hey nigger, like your "prison sag ".

pound-me-in-the-ass prison

A place that is best to avoid. But if you are sent to one, the secret is: kick someone's ass your first day, or become someone's bitch.

"We're not going to minimum-security white-collar resort. No, we're going to a federal pound-me-in-the-ass prison!"
