One who, during PvP in an MMORPG, turns their character to face their foe using their keyboard rather than their mouse. Due to the glacial speed of turning in this fashion, it will inevitably result in a severe beating from fleet-fingered, mouse-turning opponents. Used in WoW to describe those players who are completely lacking in PvP skills.
"I don't think that guy even landed a hit on me! Total keyboard turner!"
