An extreme anger over a video game; commonly associated with World of Warcraft. While there are many nerds that rage over pixilated dragons and gnomes, the reddest nerd of them all is a narcissistic asshole named Antigalactic.
Stop nerd-raging, it's just a game.
The amount of nerd-rage in here is making me uncomfortable.
I was nerd-raging so hard I beat a puppy to death with a kitten.
