Tragos can mean 'drinks' (alcoholic beverages) or 'gulps'. In this song, it's used in a double sense that makes it particularly interesting.
Initially, the artist sings about "malos tragos" (bad gulps/moments), referring to the difficult experiences and emotional pain he endured. Later, he mentions alcohol as a recommendation to forget his love, implying he took many "tragos" (drinks) to cope. This dual meaning of emotional pain and alcoholic drinks makes the word very evocative in the context of heartbreak.
Luck Ra and Nicki Nicole play a guy who is trying to sound tough about a breakup and keeps failing. He opens with a warning, “Y no vuelvas a pedir perdón” (“And don't come back to ask for forgiveness”), and tells himself the worst is already over: “Ya dolió lo que tenía que doler” (“It already hurt what had to hurt”). Then the night undoes him. He tries drinking her out of his head, “Me recomendaron alcohol para olvidarme tu amor” (“They recommended alcohol to forget your love”), and instead ends up dialing her number: “Y tomé tanto que terminé llamándote, mi amor” (“And I drank so much that I ended up calling you, my love”). The hook keeps landing on the same joke turned confession, “Y no existe un doctor para sanar este dolor” (“And there is no doctor to heal this pain”); no prescription fixes this, only she can.
Midway through, the song drops the heartbreak for a few bars of studio credits, “Con la NICKI” (“With NICKI”) and “Ramky en los controles” (“Ramky on the controls”), before snapping straight back into the chorus. That's a familiar move in Argentine RKT and cumbia 420, where the producer's name gets sung into the hook instead of printed in liner notes.
