I was playing a Zombie Apocalypse game while trying to come up with an off-the-cuff screen name that wasn't taken (I don't like adding numbers to get a screen name to work) and I got mauled and, subsequently, killed, by a shaggy, hobo zombie... Musing about getting mauled by a scruffy zombie while applying to a shaving forum, ShavedZombie worked.

Voila.
