Lusus Naturae

Lusus Naturae is a Latin term which describes "a person or animal that is markedly unusual or deformed", i.e. a "Freak". A non-furry term, it was nonetheless used by the Burned Furs on their old message board to double mean "Nature Loser", and it was mostly directed towards Furry lifestylers and/or any netizen of alt.lifestyle.furry.
