A man who is half Danish. A Halfdan is not, as some people think, someone who is 'half of a Dan'. Charactherized by the typical Danish love for beer, broad shoulders and a general viking-like physique. When a Halfdan is half Danish and half Norwegian this vikingness is particulary noticeable, and in addition his Norwegian half makes him extremely brainy.

Halfdan is a very big nerd, altough he might seem smart. He is a true definiton of a loser, he is often reffered to the biggest mistake of his parent life. He is big racist with big brain but he can always be outsmarted. The name halfdan sucks if you are smart. Nobody will like you.
