@NefThePharaoh drops a new visual for “Big Boss Chang” off new upcoming project The Big Chang Theory. The video has Nef The Pharaoh rescuing elementary children from boredom by turning up with them. After Nef is done having fun with the kids, he gets swooped up & hits the strip club to make it rain like hurricane Harvey in there. The Vallejo rapper plans on dropping his new album The Big Chang Theory on August 10th. Check this video out in the player above.
