Turbulencias is the Spanish word for "turbulence," which you've probably heard used to describe a bumpy airplane flight. It's a dramatic and vivid word that you don't often hear in pop songs.
In "Efecto," Bad Bunny uses it metaphorically to forecast a wild and passionate night. He sings, "Esta noche en la cama va a haber turbulencias" (Tonight in bed there's going to be turbulence), creating a fun and cheeky image of an exciting, unpredictable time. This clever use of language makes it a very memorable word to learn.
Bad Bunny hits you with pure, bouncy reggaeton energy in "Efecto", comparing the intense rush of falling for someone to an overwhelming chemical high. In the hook, he admits his life outside might be a mess, but everything suddenly feels flawless the second she steps in: "Mi mundo está jodido / Y me siento perfecto / Porque estás tú, aquí" ("My world is messed up / And I feel perfect / Because you are here"). When she looks at him, he starts sweating and feels like he can fly, straight-up asking what substance she slipped into his drink because he has not been the same since that first night.
He leans heavy into bold Puerto Rican street slang to explain why he is hooked. He jokes that her ex lost her through sheer carelessness, rapping "El gatito tuyo te perdió por negligencia / Y yo que no creo en la abstinencia" ("Your guy lost you due to negligence / And me, I don't believe in abstinence"). He shouts out her home base of Carolina, Puerto Rico ("de Carola"), calls out a trip to Florence ("Florencia"), and notes how she acts stuck-up now ("se puso más bicha") without losing her real roots. Even with a whole list of party substances in the lyrics, he makes it clear she is the one running the show: "Eres tú quien me controla" ("It's you who controls me").
