So the evolution of my nick is as follows. I had a bicycle that had the word Zephyr written on it. Which means a western wind. That is related to the Greek god Zephyrus.

I liked words where X make a Z sound. And also had a bit of dyslexia so my firs IRC nick was Xypher swapping the y and e.. I would also use the forms Xypherius or just Xypheri.

Because its close hemming to Cypher I found the nick would get used by others.. Though that is not my origin.

Later I would sign websites I created as The X-Urban Underground (where X was short for Xypher) and that evolved to xuu. Pronounced like zoo.
