Hang at Margaritaville wearing Hawaiian shirts and khaki shorts and no tan. Drink boatloads of Bahama Mamas (not quite sure what those are) and speak really loudly, in fact you can just sort of yell when you aren't slurring and pepper your sentences with Ya mon and fist bump every J'can you spy with "Respect, mon". A few braids with beads pasted on couldn't hurt. And cheesy bright colored plastic sunglasses. Oh you could throw on one of those hats with built in dreadlocks for good measure. That should do it. Or you could just go to Margaritaville.
