If you have a nick name that may leave people scratching their heads, explain it here. I'll start:
When I was working on my masters degree, I played A LOT of video games (it was part of my thesis--seriously!) Anyway, I play a lot of first person shooter games, and if you don't know, why you blow someone in those games, they often have body parts and whatnot thrown about. Those are called "gibbage" or sometimes just "gibs". Hence, my nickname, MrGibbage. Now, I won't tell you if I was the guy shooting and creating the gibbage, or if my body parts were creating the mess on the floor.
