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.

"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."
