The BIG List: 37 Greatest Signature Ad Libs
#37. Fabolous: "Niceee!"
→It might be the most recent signature ad lib on this entire list, but Fab's "Niiiiice" has already been a good look for his career. Since he started using it heavily on his There Is No Competition 2 (The Funeral Service) mixtape in March, the BK rapper's taken it and put it on the front of T-shirts to produce a little more pocket change. Nice!
