Machaca literally refers to shredded dried meat, a traditional dish. However, in the context of this song and regional slang, "hacer la machaca" or "ya se hizo la machaca" is an idiomatic expression meaning "the deal is done," "the money is made," or "the job is complete."
It's a fascinating word because it takes an everyday food item and transforms it into a powerful metaphor for success and completion in business or illicit ventures. This double meaning makes it unique and highly engaging for learners interested in authentic, colloquial Spanish.
This song is a conversation between two friends, or carnales, who are in a hurry to get a job done. Peso Pluma tells his partner, "El cliente no me va a esperar, carnal" (The client won't wait for me, bro). Their motivation is simple: the faster they work, the sooner "llega el money" (the money arrives). And what's the money for? To party, of course.
They plan to celebrate their success, or to "coronamos" (score), by heading out for a wild night. One of them is ignoring calls from a girl who "quiere que me controle" (wants me to control myself), but he's not interested. He'd rather listen to music and get the party started with his friend, telling him, "yo ya me quiero enfiestar, carnal, préndase un gallo" (I want to party now, bro, light up a joint).
