Le guillotine de la porte 

The fear that one may lose a body part due to any kind of door that is perceived to be closing too quickly. The phrase is said to have originated from 18th century survivors of the French Revolution who passed their remaining days in a kind of post traumatic stress disorder and obsessing about sharp quickly closing things.

"Johnny get your hand back into this elevator, the door is about to close!"

"Mom, it is just an elevator door."

"Yeah that's what you said about the bus door this morning."

"Mom I think you have le guillotine de la porte and the stories you hear are just urban legends."

"Just get your hand out of the door."
