Named after the Horde capital of Orgrimmar in World of Warcraft. Orgrimmaritis is when a max-level player sits in a capital city all day and AFKs, usually near the Bank, Auction House, or on top of the mailbox. A player contracts this disease after they get burnt out on PvP grinding, gold farming, and instancing.
Kelly: Damn, Kevin played for 12 hours a day all week? He must have his Epic Flyer by now.
Greg: You would think so, but he got Orgrimmaritis about halfway through and hasn't been to the Plateau since.
