If you're scared of something, chances are there is a scientific name for it. I scanned through and found some weird ones listed below.
Alliumphobia Fear of garlic
Apotemnophobia Fear of persons with amputations.
Caligynephobia Fear of beautiful women
Logizomechanophobia Fear of computers.
Peladophobia Fear of bald people.
Pogonophobia Fear of beards.
All the common ones are listed at the site if you want a scientific way to describe your fear of heights, snakes, clowns or sex.
If your interested SEE ALL THE PHOBIAS , and shout it out with a comment because I'm kind of interested in researching this a little more to find out why people are scared of certain things and what goes on in the brain.
