Our model Joanna was feeling the moment and flushed out two hands with this gesture, although it is usually given with one hand alone. Holding up the fingers, the demonstrator will usually give a negative look to their subject as they express the idea, "What? What are you doing? What are you talking about? Etc."
Maybe I am off with not recognizing that all of these gestures are already flaunted in some small town of Italy. But I have never seen them so utilized, and so universely understood...between 3 million citizens in Uruguay anyways.
