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..

Or some say Kosm. Is a great one of the ocean. Found washed up on a shore. Kos is the one who granted the Vacuous Rom eyes, the one who we pray to plant eyes on our brain to cleanse us from our beastly idiocy!
Ah Kos... Or some say Kosm. Do you hear our prayers? As you once did for the vacuous Rom. Grant us eyes. Grant us eyes. Plant eyes on our brain to cleanse us from our beastly idiocy!
