Cohete literally means "rocket" or "firework". It's a fun, high-energy word that perfectly captures the song's exciting, otherworldly theme.
In the lyrics, Shakira sings, "Te haré salir volando como un cohete" (I'll make you go flying like a rocket). She uses this powerful image to describe a love so intense and exhilarating it feels like being launched into another galaxy, making it a perfect metaphor for the song's passionate and escapist vibe.
Shakira and Rauw Alejandro team up for a song about a secret, super-passionate affair. The whole track is built around space travel metaphors to describe their physical connection. They sing about how "Se alinean los planetas cada vez que nos vemos" (The planets align every time we see each other), suggesting their meeting feels like destiny. It's a private thing, though. They wonder what would happen "Si ellos supieran todas las cosas que hacemos" (If they only knew all the things we do), and even joke that if their secret got out, "nos vamos viral" (we'll go viral).
The chorus is the main idea: "Despega y vente, que quiero verte / Te haré salir volando como un cohete" (Take off and come, I want to see you / I'll make you fly like a rocket). They aren't actually talking about space travel. Instead, all the talk of stars and planets is a fun way to describe an explosive physical connection that sends them to another world. It's a relationship that's a bit of a "problema" (problem), but one they can't seem to resist.
