The theatrical refers to things that are flashy or showy, often for entertainment's sake.
When we call something theatrical, we usually mean it's over-the-top, like an actor who wears a big, fake mustache and wigs. But this kind of drama isn't just for movies and theater – in everyday life, people can be theatrical too. For example, some people might use their voice or body language to get attention or draw attention away from the real issue. They might make a big scene, like a dramatic actress on stage, to get what they want. You might see this in politicians who give long speeches with lots of hand gestures, or someone who wears extremely bold and flashy clothes just to stand out.
