Caduquen comes from the verb caducar, which means to expire, lapse, or become obsolete. It's a powerful word you might see on a food label or legal document, but rarely in a trap song.
In "BOOKER T", Bad Bunny boasts, "Yo no hago canciones, hago himnos para que no caduquen" (I don't make songs, I make anthems so they don't expire). By using this sophisticated word, he's claiming his music is timeless and will never fade away, elevating his status from a mere artist to a legendary creator.
This song is Bad Bunny at his most confident, basically telling everyone he's the best in the game and no one can touch him. He's not just making music; he says, “Yo no hago canciones, hago himnos para que no caduquen” [I don't make songs, I make anthems so they don't expire]. He compares himself to the wrestler Booker T, a multi-time world champion, to drive the point home: “Soy un rey, campeón, Booker T” [I'm a king, a champion, Booker T]. The whole track is a victory lap where he looks down on his competition from the top.
He gets really specific with his boasts, too. He claims his rivals “se extinguieron como los dinosaurs” [went extinct like the dinosaurs] after he arrived on the scene. He even says that with the legendary Daddy Yankee retiring, it's his turn to take over as the boss. He's so successful that he doesn't even have to show up to award shows to win everything, and he tells haters to talk to his manager, who will also ignore them. It's a blunt and powerful statement that he's at the absolute top of his career: “Estoy en mi peak” [I'm at my peak].
