e-grudge
A hate you keep because of some jerk you only know from the internet. Usually starts with arguing on forums or fantasy teams where people are too full of themselves to shut up.
"You picked LeBron over me? I’m gonna ruin your season!", from a guy who’s never even met you.
"I’m gonna beat you in this league, and you’ll regret it.", said by someone who’s never even played the game.
He called me a donkey on Twitter. I now have an e-grudge against him. I will haunt his dreams.
