This gesture does not mean "Delicious!"!

Hello everyone! As a native Italian speaker (from Rome), I’ve noticed something interesting. So many of my foreign friends are convinced that the famous gesture—fingers gathered together, moving up and down—means “Delicious!”. But in reality, we Italians use that to say something like “What do you want?” or “What are you talking about?”.

Now I’m wondering: how many other Italian gestures or expressions get misunderstood by language learners? Have you ever used a gesture or phrase thinking it meant one thing, only to find out it actually meant something totally different?

As an Italian teacher, I love explaining not just the language, but also all those little cultural details that you won’t find in textbooks. So, tell me —have you ever had a misunderstanding with Italian hand gestures? I can explain to you their real meanings if interested. Thanks! :D
