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.

KO

Stands for a "Kill of Opportunity."
Could be a noun describing the target, or a verb describing how to kill the target.

When both Sadam Hussein and Usama Bin Laden arrive for the exchange, sniper teams 1 and 2 will take both targets out. Consider any other armed associates at the scene a KO.

We can't risk him getting captured. I don't want to go to jail while he goes free just because that child-raping pos cried police brutality. No, if any of us get a clean shot, we KO his ass! Understood?
