Take your cocktail shaker and fill with ice.
Add rum, malibu, lime juice, nutmeg, cinnamon and sugar.
Shake vigorously and strain into your tumbler.
Spear your slice of lime and pineapple chunk on a cocktail stick and add as garnish.
Enjoy! And when the Charybdis makes the room spin, tell it in no uncertain terms that you will not be taken by the sea.
