The theme comes from Disney's Pirates of the Caribbean film series, which began with The Curse of the Black Pearl in 2003 and follows Captain Jack Sparrow and his crew across the high seas. The galloping orchestral piece, widely known as He's a Pirate, became the musical signature of the franchise and was reused across sequels, trailers and theme-park attractions. Its popularity online grew as creators used the short, instantly recognisable melody to signal adventure, mischief or a dramatic entrance, keeping it a staple of pirate edits and travel videos years after the first film.
