In France, this gesture is known as la barbe, or the beard", the idea being that the gesturer is flashing his masculinity in much the same way that a buck will brandish his horns or a cock his comb. Simply brush the hand under the chin in a forward flicking motion. While not as aggressive as flashing ones actual genitalia, this gesture is legal and remains effective as a mildly insulting brush-off.
Note: In Italy, this gesture simply means No.
I thought the Italian hand gesture was the fingers under the chin flicked forward. That's only one of hundreds of Italian hand gestures. That one is a mildly contemptuous gesture meaning, roughly, "nothing." You can use it to express what you got when you were expecting more (like, "Geez, could you spare it?"), or how little you care about a situation ("I couldn't care less.").
