My nickname dates from my sophomore year of highschool when I was actually on the football team. (I say actually because it is somewhat uncharacteristic) Since I did not own cleats (or sneakers), I wore hiking boots to practice for roughly three weeks. The coach fairly quickly noticed this and dubbed me "Boots". Then I had to get an email address (I did not actually have one till my sophomore year of highschool), so I tried to get Boots@hotmail.com. You can guess how well that one didn't work. I ended up settling for Boots111, and now I use it as a pretty frequent handle (that or Booticus which was a joke in my Latin class...)
