k.
My grandpa started calling me Gonzo, after the Muppet, when I was little. It caught on, and it got shortened to Gonz over the years. My dad’s side of the family (huge family, hundreds of people) have all called me that my whole life. Most of them don’t even know my real name, lol. I started using it everywhere online some number of years (I forget) ago.
See: boring.
@Walker too, so he knows why I’m not a Gonzales.
