Descaro translates to "shamelessness" or "audacity." It's a strong word that implies a lack of modesty or respect, often used to describe someone's bold or impudent behavior.
In the song, Maikel Delacalle uses it when he sings, "Ma', deja tu descaro," which can be interpreted as him telling the woman to stop playing games or being so brazen with her intentions. It adds a layer of intrigue to their dynamic, suggesting a playful yet challenging interaction.
The whole song is one demand for a straight answer. "Aún no me ha quedado claro / Si te gusto yo o si te gusta él" ("It's still not clear to me / If you like me or if you like him") opens it, and everything after is Maikel Delacalle circling that question while she keeps him waiting. He knows what she is after — "Que tú quieres Louis, Maison Margiela" ("That you want Louis, Maison Margiela") — and he draws the line at the performance around it: "Tú quieres la movie, no estoy para tu novela" ("You want the movie, I'm not here for your drama"). The sharpest detail is domestic rather than glamorous: when she walked out she cleared the fridge as well as the wardrobe, "Te llevaste hasta la comida de la nevera" ("You even took the food from the fridge").
The hook stays conditional, and that is the point — "Y si en verdad tú a mí me quisieras / Al fin te decidieras" ("And if you really loved me / You'd finally decide"). He is not asking her to come back, he is asking her to choose, and he offers to do the driving either way: "Te salgo a buscar por la carretera" ("I'd go out to look for you on the road"), as long as "Que el otro no se entera" ("So the other one doesn't find out"). Eladio Carrión's verse switches the register from complaint to admiration, tracing her nerve back through her family — "De madre Mari, de abuela Juana" ("From mother Mari, from grandmother Juana") — and landing on "sangre caliente como una espartana" ("hot blood like a Spartan"). Two men, and the answer still missing.
