Anti-Fanboy 

Somebody who hates a certain thing (usually something that has to do with videogames) for no apparent reasons, and will not listen to logic. Super annoying, and can be worse than an actual fanboy.

Guy #1: Well, the Xbox 360 does have Netfl...
Guy #2: Oh, you mean Netass? Anything associated with the Xbox 360 sucks, and if you like it you're a faggot.
Guy #1: Anti-fanboy.
