A Game Master or in Anarchy Online, a Genetic Manipulator which sounds gay.

Basically this being is rude, nasty and avoided at all costs. They think they know how to play the game but they have no idea at all, in fact some, especially in Anarchy Online are only learning how to be rude and totally lame there, before they move to the next Funcom failure, Age of Conan.

GM: 'fuck off'

player: 'I'm being harrassed help me please'
GM 16hours later : 'fuck off bullied noob'

Player: ' Can you tell me how to trade as I am really new and I want to know more about Anarchy Online?'
GM: 'fuck off you total noob'
