[DCRM-L] hanging chad?

Hi Folks:

What do you call the flap that occurs when a corner of a leaf of paper has been folded at a 45-degree angle within the text block and has missed the blade of the guillotine therefore showing the original margins before they've been trimmed? 

I thought it was just called a flap but it's not in Carter's ABCs. I remember someone had a name for it.

Thanks!

Nina
