KOS

Kill On Sight

If someone is KOS that means you devour them right when you see them no questions asked.

Level 126: "Sorry kid but your clan is KOS so I've got to kill you."
Noob: "But I just want to play the game man, come on I'm almost done with this quest..."

KOS

To KOS is to "kill on sight" in a competitive game. These are basically the trolls of said game, their tactics varying from spawn killing to using glitches to their advantage.

I was going to win Black OPs, but some player named SpankieDavid5422 collected guns on spawn and pretty much KOSed the entire server.

KoS

Short for the Kings of Sniping. An organized gaming community with basic rules and a well-developed ranking system. Originally a Halo 2 clan, KoS has expanded their borders and now has branches in many games, mainly Halo 3 and Call of Duty 4. Do not have to be a pro at sniping to become a member. However, KoS does have H3 and COD4 teams strictly for MLG, so if you think you're pro, you can try out for their A or B Team. No age limit to join. KoS gamertags are not required to rank up. Color/Emblem requirement is up to each squad's choice. There are a lot of generals in the clan that sell level 50 accounts.

KoS is organized into divisions. Each division is divided into 10 sections, with 10 squads per section. KoS currently has 2 divisions: Division Friendly Thunder (FT) and Division Angels of Death (AoD).

Clans Currently Allied with KoS: MLG XILED, New Age Crusaders (NAC), K9Undercarriage (K9U), and Fallen Angels (xFAx)
