Chavalo is a colloquial term used in some Spanish speaking regions, particularly Mexico, for a "kid" or "young guy." It's more informal and regional than common words like "niño" or "joven," giving the lyrics a street level authenticity.
In the song, the artist sings "Desde chavalo siempre le intenté" ("Since I was a kid I always tried"), using the word to look back at his younger self and the dangerous life he was already drawn to from a very early age.
This song, "Pressure," by LEGADO 7, is all about the come-up and the hustle! It tells the story of someone who started out low-key, driving a "toyotita bajo perfil" [low-profile Toyota] and not showing off. Their main goal was always to "hacer billetes para la familia darle por venir" [make money to provide for the family].
It wasn't an easy road, as the lyrics say, "Mi historia no fue fácil por aquí, Le batallé macizo pa' subir" [My story wasn't easy here, I struggled hard to rise]. But now, things are different. From a young age, they were always trying to make things happen, even "moviendo libras una dos o tres" [moving one, two, or three pounds]. The song even mentions tagging walls with "Rusel en todos lados lo plakié" [I tagged Rusel everywhere]. Now, clients come from everywhere, even "mandamos paletonas Con 400 libronas hasta Nueva York" [we send big pallets with 400 big pounds to New York]. The artist, known as "Pressure," is all about East LA, exclusive Jordans, and the best weed, living the "vida peligrosa" [dangerous life] in Los Angeles, California, and always making sure the crew gets a piece of the action too.
