Moribundo means 'dying' or 'on the point of death'. It's a very dramatic and literary word that you won't often hear in everyday conversation.
In this fiery song, Natti Natasha uses it to wish her ex a terrible fate, singing that he "termines moribundo de amor" (end up dying of love). It’s a powerful way to describe being completely consumed and destroyed by a broken heart, perfectly capturing the song's vengeful tone.
Dominican singer Natti Natasha is completely done with giving second chances in "Desde Hoy", and she does not hold back on the drama. Instead of moping over a breakup, she kicks off the track by declaring herself in charge of her own feelings with "Desde hoy reinvento mi universo" ("Starting today I reinvent my universe"). She compares her broken trust to a dead plant—"Una margarita después que marchita no vuelve a ser una flor" ("A daisy after it wilts does not become a flower again")—and laughs at the thought of forgiving betrayal. In fact, she bluntly refuses to forgive "un buen perro" ("a real dog"), using an insult you will hear across Latin America for a shameless cheater who has no clue what love means.
What makes this track wild is the spiteful curse-parade she unleashes on her ex. She doesn't just wish he moves on; she hopes "el agua de tu fuente se contagie de veneno" ("the water in your fountain gets poisoned"), that everyone detests him, and that a literal storm cloud follows him around at night ("Que una nube te persiga"). Calling him fake and immature, she looks forward to the day his goals fall apart so she can laugh directly in his face. It is extreme, petty, and packed with colorful expressions for anyone needing to close the door on a bad relationship.
