This gesture, often called the "chin flick," is widely used among Italians and persons of Italian ancestry. It is a gesture of contempt, somewhat less rude than giving a person "the finger." When used in the United States, it usually means "Bug off, I've had enough of you." Not a polite gesture, but not a particularly hostile one, either.

One hand gesture my mother taught me was "cutis." It has an Indian (Hindu) meaning accosiated with it. First, make your hand into a fist with the thumb sticking out. Second, hold up your thumb to your two front teeth, put the nail into your mouth, and flick it. While doing this say "Cutta". It is basically **** you and your family too.
