Chabiando is a colloquial and somewhat informal term derived from "chamba," which means 'work' or 'job' in many Latin American countries. It implies 'working hard' or 'hustling'.
In the context of this song, it refers to the protagonist's early days of 'hustling' or 'working' in illicit activities, emphasizing his journey from humble beginnings. It's an interesting word because it's not standard Spanish, offering a glimpse into regional slang and the song's gritty narrative.
Gerardo Ortiz's "El Muletas (En Vivo)" drops us right into the world of a character known as "El Muletas" (The Crutches). He tells us he got this nickname because he was "rengo" [lame] after a motorcycle accident: "Por que anduve rengo me dicen muletas tuve un accidente / En la motocicleta."
He's not just talking about his past, though. El Muletas is currently behind bars, saying, "hoy estoy tras las rejas" [today I am behind bars]. But even from jail, he claims to be causing trouble for his enemies, making them endure "unas noches perversas" [some perverse nights]. He also openly admits to selling marijuana: "vendo mariguana." He's building up his crew, too, stating, "ya somos 200" [we are already 200], and he's ready for a fight, even against the government. It's a pretty blunt introduction to a tough character!
