Hm thought I told this story already
Maybe not.
When I was a white belt in both taekwondo and hapkido, I went to my first tournament and did really well: I got first in forms and sparring.
My TKD instructor asked, "How did you do?"
Excited by how well I had done, I said: "I dominated!"
He laughed. My HKD instructor arrived shortly after this and my TKD instructor told me, "Tell him how you did."
So I told him, "I dominated!" and HE laughed and said, "Ah, The Dominator, eh?"
So my TKD laughed and said, "Now you've done it! Once you get a nickname in Moo Sul Kwan, it tends to stick. Your only hope now is to live up to it."
So I trained hard and continued to do pretty well as I went up through the ranks. I remember at one point — blue belt*— walking in front of the spectator stands and hearing a couple lower ranked competitors from another school whisper to each "That's the Dominator!" in awe.
I figured I had accomplished my goal of not letting the nickname become ironic
Somewhere along the line, I started doing some online gaming beginning with World War II combat sims, in particular one called Warbirds.
In the beta phase, you could only have four characters. For various reasons (I forget exactly why, maybe lost passwords?) I ended up going through a couple variations such as
"dom-" and "-dom"
and eventually used "zdom" as in "zee Dominator" (as a variation of The Dominator)
So there it is: zDom
