Well, I've had a few...
1) Al. This is because I apparently "bear a resemblance" to an anime suit of armor. What the dukar, guys.
2) Jim. Simply because my internet alias is Jim, and it's what I use as my name on Melee, because anything else I like to be called won't fit.
3) Tron. All the people who called me this mostly left. This was because on our "Disney Dress Up Day" last year, in the midst of all the Mickies and Princesses, I was Tron. Greetings, programs.
4) Hey, get out of my way!...This is the most frequent one I hear.
