Well, my name came about a year or two ago when I was playing an online game called Blockland (Please tell me someone out there has heard of it). One of my friends was playing, and he was very big with Star Wars references, and he built a Sith academy. I played along with it, and he gave me the name "Darth Saurous", and it kind of stuck. So, now I use it with several names in different places.
