Back, not long after my third son was born, my wife, the Prairie Flower, started calling the infant, during her matriarchal dealings with him: "You little Booger". The name stuck to him as a toddler "Booger". As he got older, I'd occasionally call him "Booger Man"...then "Mr. Booger Man"...and over time I reversed it to "Goober Man", i.e. "Mr. Goober Man"...for no reason, just did. One night, in prehistoric times, I was on the early internet...and I was asked for a moniker. Initially, I was stumped and bewildered. I quickly opted for this: "Mr. Guberman". I was a designer for early squad based WWII sims...used that name for a long time. When I started flying (i.e. Aces of the Pacific, et al) and knowing combat pilots like to have their call name in one or two syllables, preferably, I adopted the name Gubi. That's about it, I guess.
