A person- commonly found at a local bar, gym, or a sporting event- who feels no one alive is smarter or more knowledgeable about a sport, and always rambles on about it in a loud, condescending, and arrogant demeanor.
"That asshole at the bar thinks no QB is better than Johnny Manziel. He won't shut up about it or stop arguing with people about it....he's super Fan-noying!"
