What's the one sound that makes you cringe?

What is your nails-on-a-chalkboard sound (besides actual nails on a chalkboard)?

Mine is when someone is reading and they have a page between their two fingers and they rub their fingers together on the page. I can't really describe what sound that makes but I hope you guys know what I mean.

I cringe every time I hear that sound. If I know the person doing that I'll yell at them and if I don't I will get up and move away.

What sound sends shivers down your spine?
