e-tough guy
An e-tough guy is a man who spends all his time in online games making his character look like a superhero, but in real life, he can't even lift a bag of groceries. He insults people online because he's too much of a f***ing baby to deal with real problems.
In chat: You’re a f***ing nobody. I’m gonna beat you up and take your gold, you weakling.
DM: I’m gonna send my friends from the CIA to your house and make you eat a whole pizza in one bite.
In-game chat: You’re just a tiny, f***ing mouse who thinks he’s a lion.
