Cagué is a colloquial and somewhat vulgar term that literally means "I pooped" but is commonly used in Spanish slang to mean "I messed up" or "I screwed up."
In the song, the artist sings, "Porque yo nunca fui el que la cagué" (Because I was never the one who messed it up). This phrase is a strong declaration of innocence, emphasizing that the blame for the relationship's failure lies with the other person. Its informal and impactful nature makes it a memorable and engaging word choice.
The song is a phone call the singer has decided not to take. It opens mid-realisation — “Mientes y yo creyéndote” (You lie and I believe you) — and by the second verse the positions have swapped: “Y ahora que me ves mejor te acercas” (And now that you see me doing better, you come closer). The ex wants another chance, and the chorus is the answer, repeated until there is nothing left to discuss: “Ya no me llames, bebé” (Don’t call me anymore, baby), with the blame set down once and left there — “Porque yo nunca fui el que la cagué” (Because I was never the one who screwed it up).
What keeps it light is how amused it is. There is a voicemail gag near the end — “Y si te da el contestador / Deja tu mensaje, mi amor” (And if you get the answering machine, leave your message, my love) — followed straight away by “no prometo, baby, volver a llamarte” (I don’t promise to call you back). The Argentine vos runs through it, and the boast that lands hardest is a national one: “Y vos te estás perdiendo a la más rica de Argentina” (And you’re missing out on the finest girl in Argentina), signed off at the last line as “Es Argentina mami” (This is Argentina, mami).
