The brown mark 

The brown mark is a sign someone is out to get you. Usually done by the act of shitting on/in someones bag. The sign is more extreme if the shit starts in the bag and goes out onto the ground in one long trail.

The Brown Market 

Like the Black Market, only all the illegal items you will ever need come from your fellow inmate's asshole. Hence, brown.

Guard Falzone: Listen, just tell us where you got the melon baller.

Prisoner: (sigh) Jerry's asshole.

Guard Falzone: You mean...?

Prisoner: Yup, The Brown Market.
