Piteado refers to a traditional Mexican craft of embroidering leather with 'pita' fiber, which comes from the agave plant. This intricate, beautiful work is a hallmark of charro (Mexican cowboy) culture and is often found on belts, saddles, and boots.
In the song, the narrator lists his 'cinturón piteado' (embroidered belt) as an essential part of the lavish outfit he wants to be buried in. This specific detail paints a vivid picture of his identity and the pride he takes in his appearance, even in his final moments.
This song is one of the most famous narcocorridos ever, and it's basically a list of instructions for a drug trafficker's funeral. The singer, Beto Quintanilla, lays out exactly how he wants to go out. He's not asking for a quiet, respectful service. Instead, he wants a huge party that celebrates his life as an outlaw. He asks to be buried well-dressed, with his gold jewelry, ostrich boots, and a deerskin vest. But he also wants to be holding an AK-47 in one hand and a kilo of cocaine in the other, telling everyone, "Quiero que me entierren / Con mi Último Contrabando" (I want them to bury me / With my last contraband).
He has a sense of humor about it all, hoping his arrival in the afterlife is so impressive that "San Pedro le diga a San Juan / Ahí viene un toro pesado" (Saint Peter tells Saint John / Here comes a big shot). He knows he might not get into heaven, and he's fine with that, saying, "Si Dios no me acepta así / Pues a ver si me acepta el diablo" (If God doesn't accept me like this / Well, let's see if the devil accepts me). The song is a bold statement about living and dying on your own terms, even if those terms are outside the law. He even wants his grave decorated with marijuana plants and to be buried with his truck, just so the world knows that the earth "No se tragó cualquier cosa" (didn't swallow just anybody).
