Choca is the third-person singular form of the verb 'chocar', which means "to crash" or "to collide". It's a dynamic word that creates a vivid image of impact or conflict.
In this fun, upbeat song, Alvaro Soler humorously sings about his inability to dance. He uses the line "Creo que mi cintura choca con mi cultura" (I think my waist crashes with my culture) to joke that his awkward dance moves are in direct conflict with his cultural expectations, making this a very memorable and funny word to learn.
Have you ever seen someone so amazing you just had to dance with them, but then remembered you have two left feet? That's the hilarious and sweet story of "La Cintura"! Alvaro Soler spots a girl who "Brilla como el sol" [Shines like the sun] and makes a huge impression. He wants to get close and dance with her, but there's a big problem.
He confesses, "Porque mi cintura necesita tu ayuda" [Because my waist needs your help]. He's a terrible dancer! He says he can't control his waist and that it "choca con mi cultura" [clashes with my culture], which is a funny way of saying he feels like he should be a good dancer. His solution is to ask her for a private practice session on the beach in the morning. It's a super fun, self-deprecating song about being so into someone that you're willing to admit you're a clumsy dancer just to spend more time with them.
