Corillo is a popular Puerto Rican slang word for a 'crew', 'squad', or tight-knit group of friends. You won't find this in a standard Spanish textbook, making it a cool word to learn!
In the song, Bad Bunny shouts, "Métase to'l mundo, to'l corillo, vamos" (Everybody get in, the whole crew, let's go), creating a celebratory scene with his friends. Learning words like corillo gives you an inside look into the culture and community behind the music.
This song feels like a late-night talk with a friend who's having a lot of feelings at once. Bad Bunny starts by setting the scene perfectly: he's watching "Otro sunset bonito que veo en San Juan" [Another beautiful sunset I see in San Juan], enjoying the simple things that people who leave Puerto Rico miss. But even in this beautiful moment, his mind is on someone else. He's full of regret, wishing he could go back and tell them things he never said. The main idea is right there in the chorus: "Debí tirar más fotos de cuando te tuve" [I should have taken more photos when I had you]. It's that simple, powerful feeling of wishing you had appreciated someone more when you had the chance.
But this isn't just a sad song! It's also a huge celebration of friendship, family, and living in the now. He's hanging out with his grandpa playing dominoes one minute, and the next he's ready to party with his whole crew, saying "Hoy la calle la dejamos desbaratada" [Today we're going to tear up the street]. He even breaks the fourth wall at the end to thank everyone for being there and tells them all to get in for a photo. He knows life is short and that you have to appreciate the people around you, because you never know if you're running out of time.
