For the sake of my fellow Researchers, I am reposting as a comment an
answer that was not correct. This is the answer that I asked the
editors to withdraw, since it describes the wrong gesture:
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.
"She makes a gesture flicking her fingers under her chin that Italians
use to say, economically, forget him, he wasn't worth it, life goes on
and you'll be better off."

"The Chin Flick gesture, in which the backs of the fingers are swept
upwards and forwards against the underside of the chin, is an
insulting action in both France and northern Italy. There it means
'Get lost-you are annoying me.' In southern Italy it also has a
negative meaning, but the message it carries is no longer insulting.
It now says simply 'There is nothing' or 'No' or 'I cannot' or 'I
don't want any'. This switch takes place between Rome and Naples and
gives rise to the intriguing possibility that the difference is due to
a surviving influence of ancient Greece. The Greeks colonized southern
Italy, but stopped their northern movement between Rome and Naples.
Greeks today use the Chin Flick in the same way as the southern
Italians... Greek architecture and philosophy expanded farther and
farther in their influences, but for some reason, gestures like the
Chin Flick did not travel so well. Many countries, such as England,
lack them altogether, and others, like France, know them only in a
Another historical influence becomes obvious when one moves to North
Africa. There, in Tunisia, the Chin Flick gesture once again becomes
totally insulting: a Tunisian gives a 'French' Chin Flick, rather than
a 'Southern Italian' Chin Flick, despite the fact that France is more
