Artist: J. Cole
Who He Dissed: Diggy Simmons
How He Dissed Him: We all thought that the beef that existed between these two was cooked. But, Cole proved otherwise when he took the stage at a concert in North Carolina last September and kicked a live freestyle that included a few bars aimed at young Diggy. "Picture me hating on a young n---- with talent," he rapped, "Album flopped, but it's cool, he caked out on his allowance." And, just like that, the beef was back on.
