Bandolero translates to "outlaw" or "bandit". It's a powerful word that evokes images of rebels and gunslingers from old stories who live by their own rules.
In "Chambea", Bad Bunny uses this word to build his persona. He sings, "Yo no soy Don Omar pero soy bandolero" (I'm not Don Omar but I'm an outlaw), a clever reference to a famous song by the reggaeton legend Don Omar. It's a bold statement that he is a new kind of rebel in the music world.
Bad Bunny's "Chambea" is a full-on flex, a song where he stares down his enemies and laughs. The whole track is built around the taunt in the chorus: "Chambea, jala, cabrón ya no te quedan balas" (Cock it, pull it, bastard, you're out of bullets). He's telling his haters they've got nothing left to throw at him. While they're busy trying to bring him down, what's he doing? "Yo siempre picheo, enrolo otra vez" (I always ignore them, I roll another one). He's completely unbothered, just chilling.
He fills the song with clever threats and boasts. He references a real Puerto Rican weather reporter, Susan Soltero, to say she predicted a "shower of bullets". He also drops a great line about power: "Si tú tienes la llave, yo tengo el llavero" (If you have the key, I have the keychain), basically saying he's the one who's really in control. He compares himself to an outlaw and says he only trusts in "God and in my .40" [caliber gun]. The message is clear: he sees himself as untouchable, like an immortal action hero who has already survived everything his rivals could muster.
