Never talk of witches on a Friday.

Ye’re ower aude ffarand to be fraid o’ witches.

As black as a witch.
As cross
As ugly
As sinful

In Italy the signs are made differently. In Naples the gettatura consists of throwing out the fore and middle fingers, so as to imitate horns, with the thumb and fingers closed. Some say the thumb should be within the middle and third fingers. In Florence the anti-witch gesture is to fare la fica, or stick the thumb out between the fore and middle fingers.

You’re like a witch, you say your prayers backward.
