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

mustard on the beat 

Said at the beginning of almost every song that DJ Mustard makes the beats for. Examples are: "I'm Different" by 2-Chainz, "HeadBand" by B.o.B and 2-Chainz, "My Nigga" by YG with Jeezy&Rich Homie Quan, and "R.I.P." by Young Jeezy and 2-Chainz.

At the beginning of "I'm Different" someone says, "Mustard on the beat hoe."

on the beat 

Indicates the arrival of a person to any location (this location is "the beat"). Must be prefaced by repeating the first letter of their name or nickname twice followed by their name or nickname. It is a more hip way of greeting someone as opposed to the standard "what's up"

I saw Richard coming towards me, so I said "Ri, ri, richboss on the beat!"
