e-tough
A guy who thinks he's a beast online but is a wimp in real life. He yells at people in chat rooms and claims he can beat anyone, even though he's probably still wearing pajamas.
@cyberbeast: I'll kick your ass in real life if you don't respect me online!
DM: You're just a nerd who can't handle a real fight.
In chat: I have a friend in the FBI who will come get you if you don't give me respect.
