Pisokatapetasmaphobia is the fear of what is behind the (shower) curtain. It's when, every time you enter a bathroom--even if it's in your own home and you were just in in an hour before!--you have to check behind the shower curtain to make sure no one is waiting there to jump out and kill you. You get bonus points if you tense up and get ready to fight them if there really is someone there.
Sure, I made this word up. But the greek roots are legit! (I think)
This is all you get during NaBloPoMo.
Do you have any crazy phobias?
