Agallas literally translates to "gills" (of a fish), but colloquially it means having the guts, nerve, or courage to do something bold. It's a vivid, informal word that packs a punch.
In this song, Jay Wheeler calls out his ex by saying she talks behind his back but doesn't have the agallas to say it to his face. This word captures a mix of frustration and a direct challenge, making it a memorable and authentic piece of emotional expression.
This song is a direct message to an ex who really did a number on him. Jay Wheeler isn't holding back; he's telling a new girl he can't trust her, and it's all because of his last relationship. He says that ever since his ex left, he feels like love is just a fairy tale and he can't trust anyone. The chorus is super blunt about it: "Ma', por tu culpa / Ya no me enamoro" (Ma', because of you / I don't fall in love anymore).
He's basically built a wall around his heart. He says she damaged him so much that he doesn't even cry anymore and claims, "No tengo sentimientos desde que te fuiste" (I don't have feelings since you left). He thinks love is out of style and has decided he's better off alone. It's a classic reggaeton heartbreak track, where he's telling her she broke him, but also that he's better off now and doesn't need her anymore.
