Comerte la cara literally translates to "to eat your face," which sounds pretty intense! It's actually a passionate and colloquial Spanish expression that means 'to cover your face with kisses' or 'to kiss you all over'.
In "PROMESA", ROSALÍA lists this among a series of intimate moments she wants to share with her lover. It's a perfect example of how Spanish can use vivid, physical imagery to express deep affection and desire.
PROMESA is a joyful, romantic track where ROSALÍA and Rauw Alejandro exchange sweet and quirky vows about sticking together through thick and thin. The singers remember a clear night without rain, where a solemn promise was made: “Una promesa nunca es pa' mirar atrás” ("A promise is never meant for looking back"). They lean into the idea that gut feelings beat logic every time, confessing that “pesa más el corazón que la razón” ("the heart carries more weight than reason"). Even if one of them slips away like a pearl dropping to the bottom of the ocean (“como una perla que volvió al fondo del mar”), they are confident they will find each other again.
What makes the track so charming is its list of specific, everyday daydreams. They want to eat cherries together, climb mountains, and jump into the water naked. Rauw even drops casual Spanish idioms like “comerte la cara” (literally "to eat your face," which is a playful way to say giving someone lots of passionate kisses) and “tener plata” (using Latin American slang for "having money"). From building a wooden chair with bare hands to pouring out a hundred bottles just to laugh, the song turns a grand pledge of devotion into a fun, down-to-earth adventure.
