Wikipedia Bitch 

Someone who changes information on Wikipedia, most likely false information, solely for the purpose of winning an argument.

I was arguing with Mikey about James Bond being on the Sargent Pepper's album cover. So I excused myself to use the bathroom and just changed the wikipedia article on my iPhone, thus proving that I was right. I'm such a Wikipedia Bitch.
