What does melodramatic gesture mean?

Melodramatic gesture refers to exaggerated or overly dramatic body movements, facial expressions, or gestures that are commonly associated with theatrical performances, especially those characterised by heightened emotions and heightened dramatic effect. These exaggerated gestures are typically employed to convey intense feelings, emotions, or reactions in a way that is considered larger-than-life and somewhat unrealistic, often seen in melodrama, soap operas, or similar genres.
