A term coined by Kory Khener in a desperate attemp to appear as a h4x0r. His 1337 skills made other people so jelous that they accused him of hacking when he really was doing no such thing. Using this name will result in getting banned from many a server.
Also the name of the greatest band in the world from the small town of Massapequa.
Vote kick ROFLbot yo'! He's got 1137 hax like yahm or something.
