Pasarela literally translates to "catwalk" or "runway". It's a central theme in the song, as Daddy Yankee describes a woman who treats the street like her own personal fashion show.
This word is interesting because it elevates an everyday setting (the sidewalk) into a glamorous stage, perfectly capturing the song's vibe of confidence and style. It's a memorable word that paints a vivid picture of the song's subject.
"Pasarela" turns a city sidewalk into a runway, and Daddy Yankee spends the whole song announcing it like an emcee. He counts through his imaginary lineup, "Modelo uno, rótate" [Model one, rotate], "Modelo dos, rótate" [Model two, rotate], before handing the moment to the woman actually walking past him: "La acera es tu pasarela, lúcete" [The sidewalk is your runway, show off].
The rest of the song is him losing his composure over it. He says his neck feels like a fan from watching everyone pass, "Me tienen el cuello como un abanico" [They've got my neck like a fan], "De lado a lado, de lado a lado" [From side to side, from side to side], and admits he wants to stay with all of them at once. The hook keeps coming back to the same instruction, "Con tu estilo mátalo" [Kill it with your style], because he isn't picking a favorite. He's just narrating the block like it's fashion week, and the last line says so outright: "Fórmate un escándalo" [Make a scandal].
