Short for the "Grey Wizard," a Grizzard is an extremely reclusive individual with premature grey hair. Rarely seen outside of his lair except to seek sustenance, most of a Grizzard's time is spent playing video games and contributing little to nothing to society.
The Grizzard didn't leave his room today...as expected.
