Estrellé comes from the verb estrellarse, which means "to crash". It's a powerful word that creates a dramatic and vivid image.
In the song, Rauw Alejandro sings, "Me estrellé en las curvas de tu cintura" (I crashed on the curves of your waist). He uses this intense metaphor to describe being completely and uncontrollably drawn to someone, as if he's had a powerful collision with his own desire. This poetic line is a memorable example of modern, figurative language in music.
This song is pure, unfiltered anticipation. Rauw Alejandro is waiting to meet up with a woman he's completely obsessed with, and he cannot wait another second. He's so confident about how the night will end, singing, "No sé cómo voy a pasar / Pero sé cómo va a terminar" (I don't know how it will happen / But I know how it will end). The whole vibe is very cinematic and luxurious; he even brags that "Mi Lambo' pega con tu cartera" (My Lambo' matches your purse).
He sees their connection as something almost out of this world, describing it as a movie and feeling like he's on the verge of insanity over her: "Estoy al borde de la locura" (I'm on the edge of madness). He's convinced she feels the same way, even if she's playing it cool. He asks, "¿Por qué te me resistes? / Si tú me deseas, ma'" (Why do you resist me? / If you desire me, ma'). It's a classic reggaeton track about overwhelming desire and the thrill of the chase.
