e-grudge
A grudge you hold against someone you only know from online. It starts when you argue on message boards or fantasy teams and they can’t take a joke.
He called me a ‘noob’ and now I have an e-grudge. He will die in a fire.
He kept bashing my draft choices. I now have an e-grudge and I will beat him in the league.
He insulted my dog. I now have an e-grudge and I will ruin his life.
