This is a cocky little love song about opposites attracting: "Tú coquette, yo, malandrón" (you're coquette, I'm a bad boy). Coquette here is the girly, bows-and-pink aesthetic, and malandrón is a rough, troublemaking guy. And she likes it: "te gustó la mala influencia, la delincuencia" (you liked the bad influence, the delinquency).
He flexes the whole way through. A "bolsita Dior" (little Dior bag) and "un billetal" (a pile of cash) for his princesses, a TRX (a Ram TRX pickup) "zumbando por los cerros" (buzzing through the hills), and the very Mexican slang es lo verga (it's the best, a vulgar way to say "awesome"). My favourite bit is how he tries to sound respectable: "Dile a tus papis que soy bien tranqui" (tell your parents I'm super chill), right after mentioning a Scar rifle riding shotgun. Not convincing! Fierro is a shout meaning roughly "let's go, full power," and cantón is slang for home: "hoy no llegas al cantón" (you're not making it home tonight).
