A very, very stupid word used to try and rob 'fans' of something of their credibility and validity. Usually used in the video gaming world, and employed by those who could be described as 'fanboys' themselves.

The word totally fails as an insult, and serves only to make the attacker seem incredibly childish. It also fails in that nobody is ashamed to call themselves a 'fan' of something - are they?
Ooooh, don't call me a FAN, I'll be so offended.

Get the fanboy mug.
1. One who is overobsessed with a particular game, movie series, or anime, to the point of calling anyone who says otherwise about said franchise inferior.
2. See Sega Slayer.
3. See sonyroolz.
Those Nintendo fanboys won't shut the fuck up about how Sega and Sony's CEO's should suck each other's penises.

What most (not all) FFVII fans are.
Fanboy: FFVII is da shit! Sephiroth is the best villain!
Me: What did he do to be so good?
Fanboy: He killed Aeris and he destroyed Cloud's hometown!!
Me: So that makes him the best villain?
Fanboy: yes!
Me: Well, Kefka destroyed 3 villages, killed hundreads of people, almost entirely destroyed the world. And you're saying Sephy is the best?
Fanboy: Shut up!
