Sandungueo is a vibrant and rhythmic word that refers to a style of sensual, energetic dancing, often associated with reggaeton and Caribbean music. It evokes a feeling of movement, rhythm, and fun.
In the song, Eladio Carrion uses it to set the mood, stating, "Este sandungueo es pa' las mujeres" (This sandungueo is for the women). It's a less common, more colloquial term than a generic word for dancing, making it interesting and unique to the genre and context of the song.
Eladio Carrión and Cris MJ turn a night at the club into the whole song. The hook, "Dale, mami, bang-bang" ["Go on, babe, bang-bang"], sets the tone, and the verses stay right there with it: "Y ven, perréame como en el 2010" ["And come, grind on me like in 2010"] is a straight callback to reggaetón's earlier run, and "Falda corta como Mía, RBD" ["Short skirt like Mía, RBD"] uses the old Mexican pop group as shorthand for the look across the room.
From there it's a simple chase. He clocks her, she clocks him back ("Me miraste, te miré, pues ven, bebé" ["You looked at me, I looked at you, so come, baby"]), and the chorus just keeps circling the same line: she says she can't stay away, and he keeps daring her closer.
