I used to be heavily involved in direct-action politics / etc. My old email address was "sedition@XYZ.com. My my first name is Chris, and since there are too many of those in the world, people started calling me "chris sedition" to parse me out from all the other "Chris'" out there. That eventually just got shortened to "sedition."
