Puyas is a fantastic slang term that translates to 'jabs', 'digs', or 'barbs'. It refers to the sharp, pointed remarks or indirect insults someone makes towards another person.
In the song, Bad Bunny sings, "te pasas en la radio tirándome puyas" (you're on the radio throwing jabs at me). Learning this word gives you insight into the subtle art of the 'diss' in Spanish, making it a memorable and very useful piece of slang for understanding music and modern conversation.
This song is the perfect anthem for when you're in that weird middle stage of a breakup. Bad Bunny isn't totally heartbroken, but he's not exactly happy either. The main line says it all: "Sin ti no me va bien, tampoco me va mal" (Without you, I'm not doing well, but I'm not doing bad either). He's decided to move on and promises, "Pase lo que pase no te voy a llamar" (Whatever happens, I'm not going to call you), because he's finally accepted that "tú nunca me vas a amar" (you're never going to love me).
To cope, he's going out to party and distract himself, but the nights are still tough. He compares his soul to a war zone, calling it "terreno sirio" (Syrian territory), which is an incredibly intense image. He mixes this pain with classic reggaeton bravado, predicting she'll miss him when her new guy is boring and her wallet is empty. He gets pretty petty, bragging about his new freedom and even throwing a very blunt insult at her mom and her lawyer. It's a messy, realistic mix of sadness, anger, and trying to convince yourself you're better off.
