A slang term substituted in for banning, or 'exiling' somebody from a chat channel. Also can be removed from other things, such as as a board, forum, team, etc; most often online.

Origins come from Starcraft where moderators were depicted with a hammer or maul as an Icon.
"3l1t3_PwN3r has left the channel."

A powerful weapon wielded by Administrators and Moderators alike. It has unparalleled power to ban retards, trolls, hackers (1337 h4x0rz), and the high-pitched ATYO (annoying twelve year old) from chat rooms and games. It is also included in some games as an equippable item with the disputed ability to hit over 9000. Beware the hammer.
