As in it's like my name but it's not what my parent's chose to name me. Hell if I was going on that I'd be depressed. Somehow Alexander makes me cringe and most of the nick names I've had are either offensive or would take too long and too much embarrassment to explain.
In fact my avatars are probably closer to what many here have done with their usernames. I did try to come up with something inventive but at the end of the day I'm me so I used that as inspiration (read excuse).
Oh and Wildcat,
Does your's come from an old American Football movie?
