Used to play with 'Transformers' action figures with my two sons. They began calling me Dadnatron instead of Megatron. It stuck, and they signed me up for a video game one time and made my name Dadnatron as a joke. I reversed it on them, and have embraced it ever since.
I'ver been a trucker for 28 years. Truck8256 was the unit number I was driving when a cement mixer driver had a diabetic seizure and T boned my rig. I opened up the passenger door and walked away injury free. You got to keep that handle.
I am a pilot (not for money, just for fun). I was out at the field one day and it was blowing to beat the band. One guy said "the only thing you should be flying today is a kite". To which I replied "I came here to fly so I will be seein' ya..". From that day on they all called me "Kite".
In grad school we shared parts of a chemistry lab in pairs; for a while I was working next to another Paul, so people started calling us PaulyT (me) and PaulyP (him) to keep us straight. It sorta stuck in my head...
Soupyjones is the name of a horse I rode my first year guiding in the mountains. After i got out of the hills I saw an old mini series from 1989 called Lonesome Dove that had a character named Soupyjones. I stole the name for a game and it has been my handle since.
The army spent lots of time and money to make me fluent in Arabic. That was about the time that e-mail started becoming more popular, 1995ish. I needed an email address and there were no names left in English that didn't require you to misspell or add numbers so I decided to use a different language. The word "moomtaz" in Arabic means "excellent". I just thought it was a cool sounding word. It has been my email address and all around interweb name since.
