Not a typo whatsoever, the fear of chewing gum really does exist and it is known as Chiclephobia. Most people with this phobia are scared of actually chewing gum themselves, coming close to a person chewing gum, and the sight of previously chewed gum. Hmm, odd. Oprah Winfrey is the most famous person to have come out with this phobia. It isn’t a joking matter either, as this phobia is known to induce panic attacks even.
Pamela Anderson is known to suffer from Spectrophobia or a fear of mirrors (and when you’re someone like Pamela Anderson it doesn’t make any sense but no one gets to choose their fears). The root causes vary from fear of the supernatural to body image issues, each person is different in their extent of phobia.
