Hand-waving

Hand-waving is when someone uses their hands to make exaggerated gestures while they talk. It's like pretending to conduct an orchestra without any music or dance without any beats. People often do this when they are trying to explain something or express their emotions. It's a way of making their point more interesting or understandable. It can also help them emphasize certain words or phrases or to show enthusiasm or excitement. Think of it like playing pretend to really make your point stand out!
