Splattermatterphobia 

The uncalming fear of what may be on the underside of the toilet seat in a public bathroom.

Someone before you may have made some porcelain percussion with their toilet muffin pasted to the seat and made a heck of a mess on the under side. You are afraid to touch the seat and lift it up! This is Splattermatterphobia!
