"Dogboy" came first. I got a new Rotty puppy while I was in Test Pilot School, and was going home in the middle of the day all the time to let it out, and feed it. So, the guys started calling me dogboy. Then, later in the course, when my "bad attitude" started showing stronger, they started calling me "Outlaw". They never could figure out which one they liked, so started calling me both.
