My older brother is a computer geek, and as such, he was given nicknames that was geek-related. He worked up at a cub scout camp, and he took upon him the nickname "Dijjithedde" ((or something like that...)), after his obsession. The nickname was popular there, to the point that the staff there decided to name the next brother to work there "Dubldijit". As a younger brother, I decided that that "trend" was cool, and decided to leave space for my twin to have the name "Trpldijjit" or something, so I made my name "Cwadrupldijjit" to carry on the tradition.
However, my brother decided not to follow that same idea, so he is known by other means. Same as my younger brother...
