Patrona is the feminine form of patrón, meaning a boss, leader, or person in control. In the song, Becky G uses it as a bold self-title, presenting herself as the powerful woman who calls the shots, as in “Ya llegó la jefa” (“the boss has arrived”).
"PATRONA" is Becky G walking in and announcing that she runs the room. She opens by warning a man, "Papi, te aviso / Que no pido perdón ni permiso" [Babe, I'm warning you / That I don't ask for forgiveness or permission], and from there every line is about who is in charge. The title word means "boss lady", and she leans on the contrast between looking sweet and being dangerous: "Siempre con carita angelical" [Always with an angelic little face], then "Una asesina profesional" [A professional killer].
The hook flips into English and gets cocky and funny about it, with "I ball like Maradona" next to "La mami que controla, que te controla" [The babe who's in control, who controls you]. The chanted "Esto es pa' que" [This is so that] keeps cutting off before she says what it is for, which is the joke: she doesn't owe anyone the end of the sentence. It closes on "Ya llegó la jefa" [The boss has arrived], which is the whole song in four words. Good for learners who want everyday Spanish for bragging, warnings and slang like "pa'" for "para".
