Juju on that beat

Essentially "juju on that beat" is a saying for dancing the popular song "Juju on that beat".
Starting as a challenge across social media, it has now converted into a meme.
Just like "vibe check", this meme is used as a sentence of regret of what you did wrong.

Person 1: You didn't juju on that beat, time to die...
Person 2: NOOOOOOOOOOOOOOOO
