Parafoot
A parafoot is something every one does, thinks about, ect...but NEVER talks about.
Have you ever scared yourself? Like, have you ever been outside, by yourself, late at night and you look behind yourself making sure no one is there? Well that's a parafoot, you never tell someone: "I looked behind myself last night walking home to make sure no one was there," you just do it! Or like when you're outside in the dark again, and you don't even hear anything but you look behind yourself and then run, you get scared from your running so you run faster and faster until you may even panic. That is an example of a parafoot.
