Pelele literally translates to 'puppet' or 'rag doll', but it's used as slang to call someone a 'wimp' or a 'pushover'. It's a very descriptive insult for someone who lacks their own will and is easily manipulated.
In this diss track, Morad repeatedly calls his rival a pelele to diminish him. He's saying his opponent is not a real artist but just a puppet controlled by others, someone weak and without substance. It's a powerful, memorable word that perfectly captures the song's confrontational energy.
This song is a straight-up diss track, and Morad is not holding back! He calls his rival a "Pelele" (puppet, or wimp), someone who is all talk and no action. He paints himself as the authentic voice of the streets, saying he's always played there while his opponent is trying to get on mainstream radio: "Yo sonando siempre en la calle, tú 40 Principales" (I'm always playing in the street, you're on the Top 40).
Morad makes fun of his rival for needing a huge team—"Cuatro guitarrista' 17 que tienen orquesta" (Four guitarists, 17 who have an orchestra)—just to make a song that nobody plays at parties. He contrasts this with his own effortless style. The whole track is a challenge, with Morad asking "¿Dónde estás escondí'o?" (Where are you hiding?) and accusing the other guy of being a fake who has a gun but doesn't shoot. It's a confident, aggressive track that establishes Morad as the real deal and his opponent as nothing more than a puppet.
