Plebes is a very popular slang word from Sinaloa, Mexico, a region known for this style of music. It's a colloquial term used to mean "dudes", "the guys", or a person's crew or entourage.
In the song, Peso Pluma sings, "Mis plebes en Suburban iban atrás" (My guys were in Suburbans behind me), referring to his crew following him. Learning a word like plebes is a great way to understand the specific culture and flavor of Regional Mexican music, as it's not something you'd typically find in a textbook!
"LA PEOPLE" plunges you straight into a chaotic military operation on the streets of Culiacán. Mexican artist Peso Pluma and Tito Double P drop you right into the narrator's escape when the army, called "los verdes" ("the greens" [soldiers]), tries to raid his spot. Instead of panicking, he slips out the back door and jokes about how close it was: "En la oficina me querían saludar / O me querían peinar" ("In the office they wanted to greet me / Or they wanted to search me"). In Mexican street slang, peinar literally means "to comb," but here it means getting searched or frisked by authorities.
What makes this track wild is the contrast between tactical survival and pure luxury. While his crew rolls behind him in camo ("camuflash") riding Suburbans, the narrator stays calm and stylish: "Piernera las botitas Dior y una scar / Bien fresco, así nomás" ("Drop-leg holster, little Dior boots, and a SCAR rifle / Looking fresh, just like that"). He does not care about losing vehicles or raided safe houses because he has plenty of backups ("Asegúrenme casas, que ahí tengo más" ["Seize my houses, I have more"]). The whole song centers on unbroken loyalty to his faction, signing off with a clear statement of allegiance: "La bandera de aquí sigue siendo Guzmán" ("The flag here is still Guzmán").
