Back in the early nineties, before PHP and fancy forums like this, when the Internet was mostly used by the government and universities, there were things called "newsgroups." As a comic book, and particular a Batman, fan, I joined the alt.comics.batman newsgroup. We were a relatively small group, and at some point we decided that we should each take on the name of a Batman character, the one that most suited who we are.
In the, rather silly, Batman comics of the 1950s and -60s, they introduced a little imp from another dimension. He wore a silly-looking Batman type of costume. He was short, pot-bellied, and a huge Batman fan--so much so, that he delighted to use his magic powers to create catastrophes in Gotham City, and then sit back and watch to see how Batman would handle them. Ultimately he was not evil, just mischievous. And he named himself Bat-mite.
Well, I am short, pot-bellied, a huge Batman fan, and rather mischievous at times, and so I chose Bat-mite. Also, I look rather silly in a Batman costume, so that sealed the deal.
