The opposite of a fanboi. This is the type of person whom will make a list of all things that, in their opinion, are wrong with a particular thing and post them in a forum, particularly gaming forums, as facts. Anyone who disagrees is dubbed a fanboi and all alternative opinions are met with derision. The bitchbot will often threaten to quit but rarely will. This threat will often be backed up with a long "Good bye" open letter about their list of opinions and why they are leaving because their opinions didn't cause change. Two weeks later they will post an "I'm Back!!!!" post.

On the rare occasion that a bitchbot does quit they will stick around in the forums for months afterward telling everyone how horrible things are even after their opinions have become so outdated as to be irrelevant.

Someone who is both robotic and a bitch.

Someone having a monotone voice and bad attitude.
