Curtis “50 Cent” Jackson was briefly arrested and fined for rapping an explicit lyric at a gig on the Caribbean island of Saint Kitts, where profanity is illegal.
From TripAdvisor.com, regarding language and etiquette in Saint Kitts and the neighboring island of Nevis:
Nevis culture has a strong religious foundation. Cursing in public is against the law. Nude bathing and topless bathing are not permitted. Beachwear is fine for the beach, but in public places it is not considered appropriate to be dressed in skimpy beach or resort clothes, such as short shorts or halter tops.
Basically, don’t act like a sailor even though it’s an island, or show any skin, even though, again, it’s an island.
In 2003, DMX was arrested at a music festival in Saint Kitts for the exact same reason. Authorities claimed he signed a contract beforehand that referenced the country’s indecent language laws, but DMX said those mothertrucking c-u-next-Tuesdays were full of caca.
