Calaste hondo literally translates to "you pierced deep" or "you cut deep". It's an idiomatic expression that describes how someone or something has profoundly affected a person, often emotionally.
In the song, the artist uses this phrase to express the depth of the emotional impact the person had on them, singing, "Mira si me calaste hondo, yo por ti toqué fondo" (Look how deep you cut me, for you I hit rock bottom). It's a powerful and evocative way to convey intense emotional pain and vulnerability.
Have you ever felt like you gave your all to someone, only for them to not appreciate you until it was too late? That's the heartbreaking story at the center of "Tarde." The singers, 3AM and Babi, trade verses about a painful breakup, exploring feelings of emptiness and betrayal. They describe being a "pobre idiota" (poor idiot) who was already feeling down and lonely, only to be broken even further by someone they trusted. The pain is so raw that one singer feels "K.O." (knocked out) while the other feels like a "flor de mentira" (a flower of lies) that can't grow.
The chorus is a powerful, repeated answer to an ex's questions. Did they love them? Do they miss them? Do they think about them? The answer is always a hesitant "Puede ser que sí" (Maybe yes), but it's immediately followed by the final verdict: "pero se te hizo tarde" (but it got too late for you). It's a declaration that while the feelings might linger, the chance for reconciliation is gone. They've decided to move on, even if it means dealing with a broken heart, telling their ex, "vete, vuela, que no quiero verte" (go, fly, I don't want to see you).
