Bailado is the past participle of the verb bailar (to dance). While "danced" might seem simple, in this song, it's part of a unique and idiomatic phrase: "Lo bailado nadie me lo quita" or "Lo bailado que nos dure."
This phrase translates to something like "No one can take away what we've danced" or "May what we've danced last us." It's a beautiful way to express that the good times and experiences (metaphorically, the 'dancing' of life) are cherished memories that no one can erase, and the singer hopes they endure. It's a memorable and uplifting sentiment that makes the word particularly interesting in this context.
"Lo Bailado" is about holding onto the good things you've already lived, even when life gets rocky. Ximena Sariñana sings that whatever has already happened between two people, nobody can take it back — the memory of it stays yours no matter what comes next.
The verses move between comfort and reassurance: after a hard season a better one follows, and a passing storm isn't a disaster. She encourages the listener to stop worrying so much and enjoy what's in front of them, because nothing lasts forever anyway, so it's worth savoring while it does.
By the chorus it becomes almost a vow — a wish that this connection, this moment together, keeps going a little longer, paired with the quiet confidence that even if it doesn't, what was shared was real and can't be undone.
