Daga means "dagger". It's a powerful and dramatic word used to create a vivid image of betrayal and pain.
In this song, Lefty Sm uses it metaphorically to describe his heartbreak, singing, "La daga en el pecho que me cargo hoy" (The dagger in the chest that I carry today). This intense metaphor powerfully conveys the deep, sharp pain of being left by someone you love.
This song is a straight-up heartbreak anthem for anyone who's ever tried to drink their feelings away. The singer is completely lost after a breakup, begging his ex to "Ven y llena este vacío / Y llévate el dolor" (Come and fill this emptiness / And take away the pain). He's not just sad; he's trying to feel anything at all, hoping that "Ahogándome en alcohol" (Drowning myself in alcohol) will make him feel alive again. It's a desperate plea, admitting he's confused and just needs her warmth back.
He feels totally betrayed, asking her why she lied about loving him. The pain is so intense he calls it a "daga en el pecho" (dagger in the chest). The story gets even more painful when he runs into her friends at a bar. He asks how she's doing, and they just laugh at him. Ouch. He tries to sound tough, saying he's changed and is a different person now, but he immediately admits the truth: "No te he olvidado" (I haven't forgotten you).
