I had a few people call me "Mr. Encyclopedia", which is a name Aexoden and Del Snizz gave me on the chatroom a few years ago. I never figured out how they knew it, either.

I use "Gauntlet", my other SN, as my Lasertag name. A few people call me "KB", but they don't know that it stands for King Bahamut.

But not really. Normally people just call me "ass."
