I was originally Demosthenes, which was derived from the alias of a character in my favorite book, and nobody could spell or say it correctly. It got shortened to Dem and Demo (which I kindof hated) and I decided that for the sake of the forum's literacy I had to change it. I changed it to the first thing that popped into my head, which was people generally commenting on how short I was. I wasn't that short, but most people still seemed taller than me).

In the past few years I've kindof wanted to go back to Demosthenes, but I've been Shorty for far longer and it would probably feel weird to other people if I changed my name this late in the game.
