Roncar literally means "to snore," but in Puerto Rican slang, it takes on a whole new meaning. It's used to tell someone to stop bragging, posturing, or acting tough when they can't back it up.
In the first line of "P FKN R," Bad Bunny says, "Si no sabes de dónde soy, no me ronquen" (If you don't know where I'm from, don't act tough with me). It's a powerful warning and a quintessential piece of Puerto Rican street slang that sets the proud, defiant tone for the entire song.
This track is a massive anthem of pride for Puerto Rico, and it's not shy about it. Bad Bunny, Kendo Kaponi, and Arcangel are basically drawing a line in the sand. The main message is right there in the hook: "Si no sabes de dónde soy, no me ronquen, no" (If you don't know where I'm from, don't front on me). They are telling anyone who disrespects them or their home to back off. The song is full of tough talk and street imagery, celebrating the hustle and the loyalty of the people from their neighborhoods, or barrios.
Each artist brings their own flavor to this theme. Bad Bunny boasts about his success, saying he became a millionaire and is respected everywhere, from the streets to the housing projects. Kendo Kaponi gets much darker, describing a place where "la vida no vale nada" (life is worthless) and detailing the crime and struggles in his Barrio Obrero. Arcangel closes it out with his own claims of authenticity and power, saying he traffics music like a drug lord and came out of prison to a million-dollar deal. It's a raw and aggressive celebration of where they come from, showing both the pride and the harsh realities of their island.
