The JK in my name stands for "Jedi_Kakarott", my original alias on the interwebs and some online shooters (mostly the original Unreal and UT). Trix came up from one of those 'hi score' games when I was younger, the first time I did it and I could only put 4 characters. This was around the same time i was learning algebra, and that the curvy 'x' was a 'variable', so I put in the first 3 letters of my real name and then 'x' for the last letter. It's stuck since.
