The word chacalón is a slang term, particularly common in Mexico, that refers to a 'tough guy' or a 'party animal'—someone who is street-smart, enjoys the nightlife, and is often associated with a certain urban subculture.
In the context of "TOTO," the line "Chacalón, suena un corridón" suggests a scene where a 'chacalón' is present, and a corridón (a type of Mexican folk ballad, often about outlaws or drug trafficking) is playing. It paints a picture of a lively, perhaps edgy, gathering, making "chacalón" an interesting and culturally specific word to learn.
Calle 24 brings us a track that's all about living life on your own terms, even if it's a little wild! He talks about "Bien loco zumbando las calles" [Crazy buzzing through the streets] and how "No existe nadie que nos pare" [There's no one who can stop us], except for God. It's a vibe of enjoying the journey and not being afraid, even when the big bosses ask him to sing and "que me cuelgue el pinche cuerno" [hang the damn horn on me] – a slang way of saying they want him to get wild and party.
He also reflects on his come-up, going from "muriéndonos de hambre" [dying of hunger] to now having "diamantes" [diamonds]. It's a blunt look at how much things have changed. And of course, there's the party life, with lines about having a "gata de copiloto" [cat as a co-pilot] and not really understanding what she's saying because he's "bien loco" [really crazy]. The song definitely has that confident, party-hard energy, moving "De cholos vagos a empresarios" [From vagrant cholos to businessmen] and enjoying the finer things, like "motita que fumo es de exporte" [the weed I smoke is for export]. It's a fun, no-holds-barred look at his world!
