Rendir cuentas is a powerful Spanish phrase that literally means "to render accounts". It's often used in business or finance, but here it takes on a more personal, idiomatic meaning: to have to answer to someone or be accountable for your actions.
In "HP", Maluma sings that the woman "No quiere un novio para rendirle cuentas" (She doesn't want a boyfriend to be accountable to). This expression perfectly captures her newfound independence and refusal to be controlled after a bad breakup, making it a key phrase for understanding the song's rebellious theme.
This song is a total anthem for anyone getting over a bad breakup! Maluma tells the story of a woman whose boyfriend cheated on her. But instead of being sad, she's decided to live her best life. As the song says, "Ella no está buscando novio / Quiere salir a joder" (She's not looking for a boyfriend / She wants to go out and party).
She's hitting the gym, looking great, and going out with her friends. A big part of her motivation is making her ex see what he's missing. She wants to "Subir un video para que lo vea él / Para que se de cuenta de lo que perdió" (Upload a video so he sees it / So he realizes what he lost). The song's title, "HP," is an abbreviation for "hijueputa," a very strong Spanish curse word she uses for her ex. She's not looking for a new relationship or anyone to control her; she just wants to have fun and be free.
