Bizzy Bone resurfaced Bone Thugs' beef with Migos by dropping a new diss track recently called "Carbon Monoxide." 

The 6-minute track starts out with a Star Wars-like intro that claims a host of rappers used Bone Thugs' flow and made millions. Bizzy also calls out "Offsides, Tequila and, most notably, the unknown third member that was left off ‘Bad and Boujee.'" He also called out 21 Savage, rapping, "Battle rapper I'm the answer/I'm blacker than Jack Panda/It's magic because I'm a Savage/That's 21/God damn I'm a f***ing gun/Public Enemy No. 1, I'm lawless."
