Huesos literally translates to "bones". While it's a common word, its use in this song is deeply poetic and romantic.
Danny Ocean sings, "Quiero repetirte los besos / Hasta conocerte los huesos" (I want to repeat our kisses / Until I know your bones). He uses this as a powerful metaphor for wanting to know someone completely, on the deepest and most intimate level imaginable, far beyond just the surface.
Venezuelan artist Danny Ocean gets wonderfully stuck inside his own head on "Vitamina," obsessing over a massive "what if." He kicks things off by asking what would have happened if they hadn't stopped kissing: "¿Qué hubiera pasado si tú y yo hubiésemos seguido esos besos?" [What would have happened if you and I had continued those kisses?]. They have been caught in a weird romantic loop for years ("Ya tenemos vario' años dando vuelta en esta situación" [We've been going around in circles in this situation for several years]), dreaming up visions of lying on the beach at sunset after reaching absolute ecstasy ("después de haber tocado el techo, bebé" [after having touched the ceiling, baby]). To him, their physical connection gives life; it acts just like daily nutrients ("Es como vitamina, tú y yo, cuando hacemos el amor" [It is like a vitamin, you and I, when we make love]).
Danny is completely blunt about wanting to dive all the way back in. He drops the everyday Caribbean slang phrase "puesta pa' eso"—literally asking if she is down for it—with the intense line "Dime si estás puesta pa' eso / O si me muero solo, mi amor" [Tell me if you are down for that, or if I die alone, my love]. It sounds dramatic, but he doubles down on the charm. Even if both of them end up dating other people ("Aunque andemos con otros amores" [Even if we walk with other loves]), he promises to keep sending her flowers and writing songs until she finally says yes. It is sweet, stubborn, and wonderfully direct.
