Coronamos literally means "we crowned" from the verb coronar (to crown). However, in modern slang, especially in this genre of music, it's a very popular way to say "we made it" or "we succeeded".
It's a powerful and triumphant word that paints a picture of reaching the top, like a king receiving his crown. In the song, Peso Pluma sings "Ya coronamos" to declare that he has finally achieved success and is at the peak of his game.
Peso Pluma's "ZAPATA" is a classic corrido tumbado flex, all about a life that's completely transformed. He lays out his new reality, which includes collector's items like a "superón / Que es edición limitada" (a limited edition pistol) and drinking fancy Perrier water. It's a big change from his start, when he says, "Comencé allá en la frontera" (I started there at the border). Now, he's got "Oficinas en LA" (Offices in LA) and drives a Lamborghini Urus while smoking weed.
He paints himself as a serious, mysterious figure who has survived a dangerous world, boasting, "Me muevo en la lumbre y todavía no me he quemado" (I move in the fire and I still haven't been burned). He's not messing around: "somos hombres, no payasos" (we are men, not clowns). The song is a straightforward declaration of success, showing how he went from a risky start to a life of extreme luxury, all while staying one step ahead of the danger.
