mostly groups of organized noobs in clubs that play on Halo. They camp and noob up a game so the other teams can't even spawn and they think they are good. They feel free to talk shit when they ain't shit. They also create "modded" games to help them win cause they suck for real.
Halo'r 1 "Dude, these clans are really noobin this game up today."
Halo'r 2. "Yea I can't even spawn cause they are all using rocket launchers."
Halo'r 1. "They are all a bunch of bitches anyways, we know we're better."

Get the clan mug.
verb: To stab or shank someone.

From a particular series of Call of Duty 4 Domination matches where a player by the handle ClanClan (slightly changed to retain anonymity)seemed to be stabbing anyone in a 5 foot radius, he was dubbed "BladeMaster" by the other players, author included.
Aww man, I just got Clan-Clan'd!

"Did you hear? Some guy got Clan-Clan'd at the club last night?"
"Yeah, I heard about that, I saw it on the news this morning."
