1. Someone who is extremely attractive. Tom's new girlfriend is a real stunner, and she's very witty to boot. My husband was a stunner, all right, but he was a lying adulterer, too.
2. An animal of great beauty or grace. Their stallion is a stunner in every sense of the word. He's actually breathtaking to behold up close.
3. Some event that is extremely exciting, impressive, or visually appealing. What a stunner of a game! It was action-packed from beginning to end! They had their wedding in Greece, and it was an absolute stunner.
