In a cocktail shaker with ice, add in the 2 oz. Pom Hula juice, 1 oz. coconut rum, .5 oz triple sec, juice of 1/2 an orange and .25 oz. of simple syrup (if you like drinks not so sweet, you can leave this out)
Put it all in and shake it all about for 15-20 seconds, until the whole thing is well chilled.
