Someone with a narcist-complex that will write everywhere what a god he is. While actually he resembles an old shoe, is utterly pathetic and has no real skills whatsoever. Rather is chating the most hidious girls up than spending time with his family. The ultimate loser you will ever meet.

Niels friend: I know (you think) you're fantastic but isn't it time for you to go home for your dinner now?
