Rompimos comes from the verb romper (to break). In Spanish, it's commonly used to say "we broke up," but Sebastián Yatra plays with the word's literal meaning in the line, "cuando rompimos, nos rompimos en partes" (when we broke up, we broke ourselves in pieces).
This powerful lyric creates a vivid image of the mutual pain of a relationship ending, suggesting that both people were shattered by the experience. It's a poetic and memorable use of a common verb that perfectly captures the song's heartbreak.
Ever broken up with someone and felt like pieces of you were left in their hands? Colombian pop singer Sebastián Yatra gets straight to the point here: "cuando rompimos nos rompimos en partes" (when we broke up, we broke into pieces). He knows the relationship is over in real life, but he proposes a wild truce. His solution is "una noche sin pensar" (one night without thinking) to drink, hit the ocean, and try to gather the scattered pieces of each other's hearts.
He admits they said "te amo" (I love you) before they even knew each other properly, rushing headfirst into the rush of a first love that is impossible to hit the brakes on. You can block him, hate him, or try to replace him, but he leaves an open invitation for "perdonarnos desnudos en el mar" (forgiving each other naked in the sea). It is dramatic, impulsive, and totally honest about wanting one last reckless night together before facing reality.
