One of our kids discovered a music genre called "Brazilian montage funk" and keeps listening to the same songs on repeat all day.
Note: they don't know a single word of Brazilian Portuguese, which I think what the lyrics are in.
No bailão, bailão (—lão, —lão, —lão)
The same line keeps getting repeated like a thousand times.

No, I don't know what it means either.
@emmy it means "in the big ball" (ball as in a dance party)
