CO Gay
When you are in jail and you are masturbating, and the Correctional officer catches you, you call out "CO Gay!" to alert the other inmates that the CO is on the look out for people jerking off.
Inmate: *Beating off*
CO: "Hey stop beating your cock!"
Inmate: "CO Gay! CO Gay! CO Gay!"
CO: "Hey stop beating your cock!"
Inmate: "CO Gay! CO Gay! CO Gay!"
