A fanboy is an obsessed fan of a specific anime, video game, or some other media, often hostile to those who disagree. Anime fanboys or otaku might engage is cosplaying, writing fanfiction, or creating fanart. Other fanboys (or the female equivelant, fangirls) of other media might do similar things and also act hostile towards those who disagree.
I just got flamed by some Naruto fanboy simply because I said it was an overrated anime.

Well, in the case of Urban Dictionary, it's someone who's only posted one definition, and that definition always bashes some other system.
I believe we all know what a fanboy is.

A fan of a certain thing who will tolerate no criticism of that thing. Most often associated with "nerdy" subjects, especially the video gaming community. Most people are likely to encounter fanboys over the Internet, as the veil of anonymity allows the fanboy to be as aggressive and arrogant as he likes without the possibility of reprisals.
Ordinary, well-adjusted game player: "Good game everyone." Hulking, stinking, fast-food loving arrogant fanboy: "OMFG YOUR A NOOB LOL I COULD KICK UR ASS UR MOM (etc.)"
