I'll start of course.

1) SCRIMM I'm going to show my age here but this name came from an actor who creeped me the heck out when I was young after watching an old 1979 horror movie called Phantasm. There is a creepy villain in the movie that goes by the name "The Tall Man" played by the actor, Angus Scrimm (stage name of course). Well, that actor's name has always stuck with me through the years so I always use this name when making gaming characters, just because of the memories it has given me and also because I simply like the name. (I have a char on the server named Skrimm as a replacement.)

2) DOOKDOOK Years ago I used to live in South Korea for several years, where I met and married my current wife. While living there and before I studied and was learning to speak Korean. Well for no particular reason at all for years I always forgot the Korean word for "monk." But the one thing I never forgot was sometimes when using the subway or trains you would sometimes see a monk there playing a small wooden instrument which he would hit and it would make a "dook dook" sound when he struck it. So, since I could never remember the word for monk itself I would always tell my wife I saw another "dook dook monk" at the train station today and still call them that to this day.
How about you guys. Any interesting character naming stories?
