What does umanwizard mean?

When I was about six years old, I thought the character "ultraman" was cool, so I named myself "ultraman" or "uman" on a bunch of online games. Then on one, probably the the sadly now defunct Dragon Court, I wanted to make a character that was a wizard class, so I named it "umanwizard", then started using that for more stuff. I was probably around 10 years old by that point.
