J_MASTER.
Made it the day the Nintendo DS came out and declared that I needed a username.

I've been saying that's where my username has come from for years, but the timeline in which I started Runescape (where I got the name) and the Nintendo DS coming out is off.
Haven't the foggiest as to how long ago that was. 7 years?
Runescape apparently. I wish I knew how I got it though.
