Chamaquito is a colloquial term, particularly common in Puerto Rico, meaning "kid" or "little kid". It's a more endearing and informal way to refer to a young person than the standard "niño".
In the song, Lefty Sm sings, "Me vienen matando desde chamaquito" (They've been trying to kill me since I was a little kid). This word adds a personal and raw touch, highlighting his difficult past and the struggles he faced from a very young age, making his journey to success even more impactful.
Lefty Sm and Jamby El Favo's "Caro" is a powerful anthem about overcoming struggles and enjoying the fruits of hard work. The title, "Caro" [expensive], sets the tone, as Lefty Sm declares, "Caro, salgo caro, salgo caro / Porque caro me costó llegar aquí" [Expensive, I come out expensive, I come out expensive / Because it cost me a lot to get here]. It's a blunt message to anyone who doubted him when he had nothing.
The song is all about living large now that success has arrived. Lefty Sm talks about spending money freely, "Ando gastando billete / Ya no la pienso pa' estrenar juguete" [I'm spending money / I don't think twice about getting a new toy], and enjoying good food. He also makes it clear that he's cut ties with fake friends, saying, "No eres mi amigo a la mierda tú vete" [You're not my friend, go to hell]. He's focused on his own path, ignoring the haters because "no saben lo que he pasado / Lo recorrido lo que he llorado" [they don't know what I've been through / What I've traveled, what I've cried]. Jamby El Favo joins in, adding to the theme of rising from the bottom, from the "ghetto," and earning respect above all else. This track is a defiant celebration of their journey and hard-won success.
