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.

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.

Banhammers are fearsome weapons wielded by the Admins, a race of genetically enhanced people who have been created to serve and to protect online communities from the evil that fills the internet. The Banhammers are mighty weapons, and must be used carefully, as whoever holds one of these weapons have power over the accounts of all others. Also known as the Faggot Banisher, the ATYO (annoying twelve-year old) Destroyer, and the Retard Bane.
