Castigo translates to "punishment" or "timeout". It's a word often associated with childhood discipline, making its use in a romantic context quite striking.
In the song, the singer tells their ex, "Vou te deixar de castigo" (I'm going to put you in timeout/punish you). This playful yet firm declaration highlights the power dynamic shift after a breakup, where the one who was hurt now asserts control, treating the ex like a misbehaving child. It's an interesting and somewhat ironic use of the word in a song about heartbreak and moving on.
MC Don Juan turns a breakup into a funk carioca victory lap. He opens with a shout-out to his producers ("DG" and "Batidão Stronda") before laying out the setup: she ended things and is now the one asking him to be reasonable — "Foi você que terminou comigo, agora vem pedir pra eu ter juízo" [It was you who broke up with me, now you come asking me to be sensible]. His answer is the hook itself: "Vai ter que aguentar" [You're going to have to put up with it], repeated over "Eu pegando outra novinha pra botar no teu lugar" [Me getting another girl to put in your place] — the classic funk brag of moving on louder and faster than the person who left.
Maiara e Maraisa answer back in the second half with the same line flipped to the feminine, "Eu pegando outro novinho" [Me getting another guy], turning the song into a duel between exes rather than a one-sided taunt. It's a track built for a car with the windows down: short, blunt lines, a beat that never lets up, and a chorus designed to be shouted back at full volume.
