e-grudge
A grudge you hold for someone you only know from the internet. It usually begins with people being too much on message boards or fantasy teams.
I had to delete his tweet because he called me a ‘muggle’ and I’m not even a wizard.
He kept telling me I was gonna lose the league. I now have an e-grudge against him.
He called me a ‘no-lifer’ because I took a break. I now have an e-grudge and he is dead to me.
