I was out hiking with the class when me and two friends started thinking about what CS names we were gonna use
After a lot of really crappy names, I came up with "Xzirox", however I was pronouncing it kinda swe-english...ish: "Ksairocks"
The name stuck with me until now, although I was called "Xzi" mainly on Maloria, and nowadays it's usually just "Ziro".
