Created the antigoon handle in middle school for counter-strike I think. One of my friends called me the "anti-goon" because I was really short and skinny.
Kinda similar to mine. My friend Dave (no, TAC, not Meniketti) sort of came up with the initial iteration back in high school. We both were into arcade games. The more stuff you had to shoot/blow up/etc., the better the game. Dave observed that the name of one space shoot-em-up game, Boskonians, was kinda neat, and that you could kinda play around with it. So taking BOSKONE, you could kinda break up the letters to get 13051 < ONE. ("13" = "B"; "5" = "S"; "1<" = "K") Mathematically, this is not true because 13051 is not less than one. BUT, you can kind of flip it on its head metaphysically. The idea was basically along the lines of the romantic ideal that one who has known love is greater than the untold masses who have not. Thus, 13,051 representing the masses who have never known love are < the one who has. 13051<ONE is thus a paradox, and "BOSKONE" thus becomes the "cool secret password" for a couple of high school boys with nothing better to do than come up with such things.
It's just one of those things that stuck through the years, and I began using shortened versions of it. Way back when common use of the Internet and email and such was still relatively new, I had to choose a username for my AOL account. Usernames had to be lowercase and had to have some numbers as well as letters. The obvious choice was the shortened form, "bosk1." I've used it in that form ever since. So both the lack of capitalization and the 1 at the end are officially part of the name, and the one isn't on there just because I knew everyone would want "bosk" as their username and put the 1 on just to show I was first.
Anyway, as I said, kinda dorky, but there you have it.
