In prison, some inmates will stir feces and urine in a container, and when they are told to exit the cell, or given their daily meals, they will throw the mixture at the correctional officers. It comes from the MSNBC show, "Lock Up: Raw."
Officer: "Come out of your cell!"
Inmate: "Fuck you!"
Officer: "Last warning!"
Inmate: "Suck my dick motherfucker!"
Officer: *opens cell*
Inmate: *gasses officer*
Officer: "Ah shit guys he just gassed me!"
