Some of these are really funny--the ones that have interesting stories behind them remind me of "trail names" that long-distance hikers often have. (Some good ones I have heard are "Sir Pees-A-Lot", "Flameboy", who must have had some sort of accident with his stove, and "Vagus" as in cranial nerve X). I've never really had a nickname other than "Andi" (short for Andrea) when I was little, and that one was really only used by my family.
