I actually use to use "X" as my callsign for all the video games I would play. But when signing up for most online stuff, they always wanted a minimum of say 3 characters. Sometimes I could get away with -X-, but most of the time I couldnt, and "XXX" doesnt really make a good name for playing games online :P
So one day many years ago I was signing up for Heat.net so I could play WarCraft II on the internet. I again was trying to use my usual name of "X" and it didnt work. Well I got all pissed off and bashed the keyboard with my hands and a bunch of random letters were on the screen...something like "alimfjhs" or some other such random assortment of letters. I then hit backspace a few times and was left with "alim". After looking at it for a few minutes, trying to convince myself I was happy with it, I for some reason added an "a" at the end and had "Alima" which has been my name in every game Ive ever played since...
