1.To ninja a tanking item from a tank and claim you need it for arena.

2.Being Really Dumb

Started from the realm Rexxar in World Of Warcraft when a noob mage need rolled on the tanking trinket: Commendation of Kael'thas and said he needed for arena then went on the rexxar realm forum and flamed the tank for being a crappy tank then got flamed world wide.
