Qué dirán is a powerful Spanish phrase that literally means "what they will say." It's often used as a noun, el qué dirán, to refer to the fear of gossip or what other people might think of your actions.
In 'Felices Los 4', Maluma sings, "No importa el qué dirán, nos gusta así" (It doesn't matter what they'll say, we like it like this). He uses this phrase to express a rebellious attitude, dismissing social judgment about his unconventional relationship.
Colombian reggaeton star Maluma takes the drama out of relationship drama in "Felices Los 4". Instead of crying over someone sneaking out at dawn—"Apenas sale el sol y tú te vas corriendo" ("As soon as the sun rises, you go running")—he simply shrugs it off. He openly admits he does not care if she stays with him or leaves with someone else ("No me importa un carajo porque sé que volverás" / "I don't give a damn because I know you'll come back"). There are no rigid rules, no formal commitments, and definitely no guilt trips.
The real punchline of the track is the chorus: "Vamos a ser feliz, felices los cuatro" ("We're going to be happy, all four of us"). It is a cheeky nod to non-monogamy, suggesting that if both of them are seeing other partners on the side, everyone wins and they can even make room for more ("Te agrandamos el cuarto" / "We'll make the room bigger for you"). Maluma brushes off outside gossip with "No importa el qué dirán" ("It doesn't matter what people say"), leaning fully into an uncomplicated arrangement where pleasure comes first and attachment takes a backseat.
