Grilletes translates to "shackles" or "fetters". It's a strong and evocative word that immediately brings to mind images of confinement and imprisonment.
In the context of "Naci Pa' La Mafia", the singer uses this word to describe being caught by the law, stating "Me pusieron los grilletes" (They put the shackles on me). This word is particularly impactful as it directly relates to the song's theme of living a life involved with the mafia and facing the consequences.
Tito Torbellino Jr.'s "Naci Pa' La Mafia" is a bold declaration from someone who feels destined for a life of crime, and it's clear he's not looking back. He talks about how quickly fair-weather friends disappear when times get tough, comparing it to how "cuando el veneno se seca" [when the poison dries up], even the flies stay away. It's a blunt look at loyalty in his world.
He's been caught before, saying "la segunda vez que caigo" [the second time I fall], but he's confident they won't get him again. He's especially unforgiving of betrayal, stating "la traición es muy corriente no se la perdonan a nadie" [betrayal is very common, they don't forgive it to anyone]. The song is all about his unshakeable identity, repeating "nací para la mafia, nunca nadie va a cambiarme" [I was born for the mafia, no one will ever change me]. Even ten years in prison, "diez años son muchos días pero son los a más horas me sirvieron para aprender" [ten years are many days but they were the most hours that served me to learn], only made him stronger and smarter. He's saying this is who he is, and he's got the talent and experience to prove it.
