KOS means Kill On Sight in multiplayer games like GMod, mostly used when someone will put up a sign on their base/building saying "KOS ANY REASON", "KOS INSIDE", etc.
Example 1:
A: Dude, why did you RDM Me?
B: The building said "KOS ANY REASON" in large red text, Cant you read??
Example 2:
A: Mayor, you know you cant make people you dont like KOS in laws, right?
B: Yea, thats FailRP, You know..

That guy just got his glasses shattered by the basketball and the ref didn't call a foul even though he's got blood in his eyes. He's going to be in trouble if it gets much worse, why doesn't he just play regular basketball instead of KO basketball? Why does he keep doing this to himself?
