To be dan is to be angry to an extent where head explosion can be readily achieved. originating in the Australian cities of Albury/Woodonga, after a local celebrity got so angry at a practical joke, that his head swelled up and became so red that it was close to exploding, and then sent abusive messages to many of the people of Albury/woodonga abusing them and threatening them. after the indecent "dan" became a popular phrase used to emphasize one's anger/frustration.
A piece of human trash. If Dan could be described in two words it would be shit and cunt. Dan is a wortless ulgy human being who deserves every bad thing that happens to him. Can also be used to describe every bad thing existence.
Example 1: Oh my God, I just got stabbed in the face and shat on by two monkeys. That was Dan wasn't it?
