SixPack - No real logical reason but I got drunk one night and while looking in the mirror I noticed my head looked a little square so I started telling everyone to call me sponge bob square head from now on. The name stuck but got simplified down to square. My username used to be dmhtfld which is my name without vowels but I wanted to make something easier to remember so I came up with A Squared. My first name has two As in it so it makes sense I guess.
