Ryan D. I think is self explanatory.
I have also used Afro Wookie, mainly on XBOX Live. I have really thick and curly hair, so when it grows out it looks like an afro. And Wookie because, well, I resemble a wookie. So a buddy of mine combined the two.
On my truck forum, as well as my original XBOX Live tag, I am radtcma. It's also on my license plate. My initials are RAD and I drive a Tacoma, hence, radtcma
