KOS

KOS is a common word used in Garry's Mod, DarkRP.
This is used as a signal to say if in my base you will be killed and there is a reason for the kill.
It should not be used on anything else but your base.

*In text above base* If in base KOS/Kill on sight.
*In text above base* If shooting in base KOS.
