Out of pure curiosity, I was wondering how you all came up with your usernames, but first, I must tell you how I got mine:
I started online gamming when I was nine years old (yeah, nine year olds online...) and I came up with all sorts of cheesy names. My first online game was on Warcraft III, and I still play today. My older brother, however, thought that all my usernames were god-awful. So, in an attempt to have me not embarrass myself, he gave me the name, "Ohyoupokedme" and it kinda stuck. I've been using it ever since.
How about you? How did you get your username?
