Bendito literally translates to "blessed". However, in the song, it's used in the very common Puerto Rican exclamation, "¡Ay, bendito!"
This phrase is a cornerstone of Puerto Rican slang, used to express anything from shock and pity to affection and endearment. In "Despacito", the line "Hasta que las olas griten 'Ay, bendito'" (Until the waves scream 'Ay, bendito') personifies the ocean, suggesting the experience is so intense that even nature has to cry out. It's a fantastic piece of local flavor that brings the island's culture right into the song.
Luis Fonsi, an artist from Puerto Rico, teams up with Daddy Yankee for a track that is entirely about taking your time when the chemistry is wild. Right from the start, he sees someone across the room and says, Tú eres el imán y yo soy el metal (You are the magnet and I am the metal). His heart rate spikes just thinking about getting closer. But instead of rushing into anything, the whole hook argues for slowing down. He sings Esto hay que tomarlo sin ningún apuro (This has to be taken without any hurry), setting up the famous catchphrase Despacito (Slowly).
The imagery stays locked on heat, dancing, and teasing patience. Fonsi wants to move Pasito a pasito, suave suavecito (Step by step, soft and gentle) until two people are pressed together. He brings his home island straight into the fantasy: Vamos a hacerlo en una playa en Puerto Rico (Let's do it on a beach in Puerto Rico). In that same verse, he jokes that they will keep going Hasta que las olas griten 'Ay, bendito' (Until the waves scream 'Ay, bendito'). That phrase, ¡Ay, bendito!, is everyday Puerto Rican slang used for shock, sympathy, or excitement, kind of like crying out 'Oh, heavens!' The ultimate goal here is pure, overwhelming passion: he wants you to lose your mind so completely that you forget your own last name (Y que olvides tu apellido).
