Mines derived from Paul, my name, and Native Beats, a drum and bass rave crew that I used to be a part of. Like suicideneil it formed my first and current E-mail account
nativepaul@hotpotmail.com and has been my handle on all the forums I visit except the City of Heroes forum which I used my characters name PuffCat for in game recognition.
For those that get the references in those names, I've given up now, but I keep that email account despite the reference as I have used it for 6-7 years and have never had a single piece of spam.
