Use a large pitcher to start making your Bahama mamas. Add the coconut rum, Captain Morgan, pineapple juice, orange juice, and Sprite directly to the pitcher.
Take a large stirrer or a large spoon and mix everything together until the various drinks are well combined.
Prepare 2 large glasses by adding 3 medium sized ice cubes to the glasses.
Pour the mixed drink evenly into the 2 glasses, making sure to pour over the ice cubes.
Top each glass off with 1 tablespoon of Grenadine. Pour it into the glasses in a circular motion to give the drink a more appealing look.
Squirt around ½ tablespoon of lime juice into each drink.
Finally, garnish the Bahama mamas with a wedge of pineapple and a candied cherry on a stick.
