1) Put the oranges, limes, sugar, and mint in a large rocks glass.
2) Muddle the leaves and citrus by pressing them with a pestle or a wooden spoon until juicy and fragrant.
3) Add the rum and ice. Cover with a cocktail shaker and shake vigorously, or stir, until combined and chilled, about 30 seconds. (In general, by the time the shaker mists up the drink is ready.) Serve.
