What's in a name?

Xavi of El diari del Xavi asked an interesting question: why or how did you choose your username? Here's the explanation for my choice:

I looked for a username that in any case should not contain a number, like 'Guido1967' or something like that, I hate those... Combinations with my name were mostly already taken or not nice and so I started looking into something independent from my real name/initials.

First of all, I like cruising... to go on a cruise ship that is... hence the "cruis" part of the username. The "air" part comes from my affection for all stuff airlines and the combination of both words sounds like "cruiser" which on one hand is what you are when you cruise and on the other hand has that ambiguous meaning to it... funny enough, I'm not a "cruiser" at all in the 'gay' sense of the word... hahaha

So, how did you choose your name and why?
