Pants that are worn below the waste line, exposing the boxers. Oversized pants make it easier because it drops as the belt is adjusted. It is believed this originated in prison. Male prisoners would wear pants that were sagging in order to have sex and not get caught. Sex is prohibited in prison and the guards would catch the male prisoners having sex or with their pants down. The idea of sagging made it easier for male prisoners to have sex and pull their
pants up as the guards approached.
Sag til you drop, bend over when you drop.
