Colivie literally means 'cage'. It's a striking word that isn't commonly found in everyday conversation or typical song lyrics, making it memorable and unique.
In the context of this song, the singer expresses a newfound desire for freedom and enjoyment, saying "Mi-e a început să-mi placă după colivie" (I started to like it after the cage). This powerfully suggests that she feels she's been confined or restricted, perhaps by societal expectations or her upbringing, and is now breaking free to enjoy life, dance, and even have a little drink at the wedding.
This song is a total party anthem from the perspective of a young woman who is just done with being told what to do. She's at a wedding where she's supposed to be well-behaved, or "cuminte" as she says. A priest even told her it's shameful and cold to act out. But she's tired of sitting quietly in the corner, declaring, "Dar eu m-am săturat să stau la colţ de masă" (But I'm tired of sitting at the corner of the table).
So, she's decided to ignore everyone. She's worked hard all day, put on a beautiful dress, and now she's going to have fun. In the chaotic wedding scene where "Toţi vorbesc, nimeni n-ascultă" (Everyone is talking, nobody is listening), she sees her chance. She doesn't care what people say; her soul wants to dance and she's even going to have a little brandy. It's a fun, rebellious song about breaking free and enjoying yourself, deciding, "Am să joc măcar o dată-n viaţă" (I'm going to dance at least once in my life).
