Day is a member of The Leaders Of Tha Free World.
Day appears frequently with his Free World crew. His first appearance was him, along with his crew, chanting "choke" in front of B-Rabbit crew. B-Rabbit actually chokes and leaves. Day is seen again when his crew is in the Parking Lot, heckling the rappers there.
Next, the Three One Third reaches up to his crew resulting in a fight.
