e-tough
A guy who acts like a tough guy online, but in real life he’s just a guy who gets tossed out of chat rooms because he talks too much and says stupid stuff.
@chatroomhero: I’m so tough I can beat the FBI and I have a super sword!
In chat: I have a friend in the FBI who can track you down and beat you up.
DM: I’m not a wimp. I can beat anyone in real life.
