Coulrophobia.Never heard of it? Then there’s a pretty good chance you are not afraid of clowns.But like the latest hysteria over clown sightings, the phobia itself can trace its growth to the internet.Kim Metz, a professor of psychology at Walsh University in North Canton, has found herself chatting a lot about clowns as of late in her classes about the fear — real or imagined.Metz said ever since the first supposed clown sighting this summer by someone’s “cousin’s brother’s best friend” spread over social media, there’s been a fear of the greasepaint.“Hysteria feeds off itself,” she said.She points out there is a supposed phobia for everything and clowns are no different.“You can be afraid of your knees,” Metz said.But clowns.
