The common nickname is Judd. This was my father's name and I've had it as a nickname since the mid-eighties. Before that is was 'red', or my wrestling name - 'big Judd Stud', used in the mid to late 80's when we would do our own WWE in the front yard and carry it over to the Cincinnati Gardens after the show was over. I had a pic of me giving my, now brother-in-law, a 'diamond cutter' the night after DDP had given one to Jake the Snake in the same ring. Pretty Cool.
As for nicknames - Judd works for me. Feel free to use that instead of my username. I even list it in my sig.
