When I was 11 years old my family finally ditched the Prodigy dial-up internet service and switched to AOL, and there was much rejoicing. Anyway, I had to create a screen name for the first time and I decided that I didn't want to use numbers and I wanted to incorporate my name. It just so happened that at this time my dad was watching the NY Giants play the Tampa Bay Buccaneers on TV and as I am sometimes inclined to do I read Tampa Bay backwards and it spelled yabapmat. So I added a 't' to the end so it incorporated my name and at that moment one of the weirdest screen names in history was born.
