nerfbat 

A term used when something in a game (generally an MMOG or FPS) is weakened considerably.

Nerfbat came about because Nerf creates harmless versions of harmful devices (swords, guns, etc).

When an MMORPG developer gives something the nerfbat, they often drastically reduce the effectiveness of said item.
