Have a good friend and former coworker, same thing. It's not the actual folding, it's when you use your fingers or nails to crease it.

Was always fun in large meetings, get bored, get Christina's attention, pick up a piece of paper, watch the panic come across her face, slowly start to fold the paper, beads of sweat would start forming on her forehead while her eyes would be pleading , Noooooooooooooooooo!

For me it's a knife scraping a plate or teeth scraping a fork.

Makes me insane.
