Boludo is a very common slang term in Argentina, where the band Migrantes is from. It literally translates to "big-balled" but is used colloquially to mean "idiot" or "dumbass."
In the song, the singer laments, "De boludo vi tu foto, ay, qué mal me hacés" (Like an idiot, I saw your photo, oh, how badly you make me feel). It perfectly captures the self-deprecating frustration of someone regretting their actions after a breakup.
Have you ever tried to get over someone by going out with friends, only to end up feeling even worse? That's exactly what's happening in Migrantes' "Dolido Y Borracho" (Hurting and Drunk) featuring Piso 21 and Nico Valdi.
The song kicks off with our guy in denial, saying "No lo acepto, lo nuestro se acabó" (I don't accept it, what we had is over). He's at home, feeling crazy, and even though his head is spinning, his ex isn't coming back. He tries to distract himself, but even partying isn't enough anymore. Seeing her photo just makes things worse, as he admits, "ay, qué mal me hacés" (oh, how bad you make me feel).
He's literally "Dolido y borracho, mezclé Fernet con vino" (Hurting and drunk, I mixed Fernet with wine) and out with his friends to avoid being depressed. The worst part? He hears she's doing "tranqui', tranqui', perreando" (chilling, chilling, dancing reggaeton), but he can't move on. He even says, "Por vos soy un tipo anti, anti-romantic y ando bien resentido" (Because of you, I'm an anti, anti-romantic guy and I'm really resentful). He knows he needs to learn to live with the memories, even though it hurts to "Arrancarte de mi pecho y de mi piel" (Tear you from my chest and my skin). It's a relatable anthem for anyone who's tried to drink away their heartbreak, only to find it's still there.
