The "Drunk Salute". Accidentally invented in the MMORPG game EvE online by a group known as Brave Newbies when a drunk commander accidentally typed "7o" instead of " o7 " (A salute in which the o represents a head and the 7 represents the arm and hand). It eventually stuck, and is now Brave Newbies' signature, and is used to taunt their foes.
