“Cuff It” is a new song by Beyonce, and to be honest, I had zero idea what she was talking about. So, shoutout to the site https://www.songmeaningsandfacts.com/beyonces-cuff-it-lyrics-meaning/ and their explanation of what the heck she’s talking about. When you “cuff” someone it means that they won’t date anyone else but you. I GUESS it is a play on the old “ball and chain.” You decide.
