Descaro translates to "shamelessness" or "impudence". It's a strong word used to describe a bold, disrespectful attitude or action, often implying a lack of modesty or a brazen defiance of what is proper.
In the song, Lefty Sm uses it when he sings, "Que no me interesa su pinche descaro" (I'm not interested in your damn shamelessness). This highlights his defiant and unapologetic persona, dismissing any criticism or negative judgment from others with a powerful and direct term.
Lefty Sm's "Volando" is a bold statement of who he is, where he's from, and why he's not changing for anyone. The title itself means "Flying," and he repeats in the chorus, "Otra vez ando volando" (I'm flying again), which can mean he's high, feeling on top of the world, or just in his own wild state of mind. He's completely himself, saying, "Así salió el muchacho" (That's just how the kid turned out) and he doesn't care who likes it. He's fiercely proud of his roots, shouting out his home state with "Soy de Sonora, del Río Colorado" (I'm from Sonora, from the Colorado River) and declaring himself a "mexicano de orgullo moreno" (a Mexican with brown pride).
He spends a lot of the song pushing back against haters and fake friends. He knows people talk behind his back, saying he's rude or that he sings nonsense, but his response is blunt: "La neta me vale macizo" (Honestly I don't give a damn). He's aware of the "traicionero' me han llamado amigo" (traitors who have called me a friend) but he just laughs it off. This isn't a song about making friends; it's about loyalty to his crew and a warning to everyone else. He's got a heavy style, he's missing a few screws, and he will absolutely not stay quiet.
