Like Gray said, my name is a little bit of a nod to Johnny Cash.
However! Back in high school, I wore a lot of black because I was insecure and it helped me kind of blend in to the background. Most people didn't even know my name, so I got "that guy in the black" a lot.
It got to a point where I decided to just own it and roll with it and I've been "ThatGuyInBlack" for a good long while, now.
