Aborrecido is a strong adjective that translates to "fed up," "hateful," or "loathsome." It comes from the powerful verb aborrecer, which means to abhor or to loathe.
In the song, Bad Bunny uses it to show he's completely disgusted with the situation, singing, "Aborrecido, estoy que me mudo pa' Kansas" ("Fed up, I'm about to move to Kansas"). It’s a much more intense word than enojado (angry), perfectly capturing the raw emotion of wanting to escape a toxic relationship.
This is the ultimate breakup song. Bad Bunny is completely done with his ex and he's not being polite about it. The title itself, "GRACIAS POR NADA" (Thanks For Nothing), is dripping with sarcasm. He makes it clear there is absolutely no going back, not even if "baje Jesucristo y nos vuelva a bendecir" (Jesus Christ comes down and blesses us again). The chorus is brutally direct: he tells her "Ya no hay pa' ti, ni bicho ni Prada" (There's no more d*** or Prada for you). He's cutting her off from everything, both physically and financially.
So what happened? He thought they were a classic love story, "Julieta y... Romeo" (Juliet and... Romeo), but then he woke up in the middle of the night and saw her texts with another guy. He feels like his only mistake was trusting her in the first place, saying "Yo fallé más que tú, pero en darte mi confianza" (I failed more than you, but in giving you my trust). He tells her that her looks don't matter because she isn't honest, a pretty powerful statement in a reggaeton song. It's a classic story of betrayal, but told with Bad Bunny's signature bluntness.
