Bandolero literally translates to "outlaw" or "bandit." It's a word that evokes a sense of rebellion and a life outside the law, often associated with a romanticized, dangerous figure.
In the context of the song, Arcángel uses it to express a return to a wilder, perhaps less committed, lifestyle after a heartbreak. He sings, "Me había quita'o y volví a ser un bandolero" (I had quit and became a bandit again), suggesting he had tried to settle down but is now reverting to his old ways. This word is interesting because it's not commonly found in everyday conversation and carries a strong cultural connotation in Latin music.
"Fecha De Vencimiento" ("Expiration Date") is Arcángel's post-breakup confession, and he opens with the bluntest line he could write: "No me siento cool, hoy me siento mierda" [I don't feel cool, today I feel like shit]. There's no easing into it after that. He walks through missing someone he knows he wronged, "Todo me recuerda a ti, todo me da vueltas" [Everything reminds me of you, everything's spinning], and admits the fix won't be quick: "Para superarte tengo que volve' a nacer" [To get over you I've got to be born again].
The hook turns the title into a promise he broke: "Creí que no teníamos fecha de vencimiento" [I thought we didn't have an expiration date]. By the last verse he stops making excuses and just lists what he did: "Me necesitaste y te abandoné" [You needed me and I abandoned you], "Por culpa tuya ahora solo ando con cuero'" [Because of you now I just mess around], closing on the admission that he's already back to his old ways, "Me había quita'o y volví a ser un bandolero" [I had quit that and went back to being an outlaw]. It's less a love song than a guy narrating his own relapse in real time.
