Nate Diaz is widely credited with creating the idea of the BMF belt, and the UFC (through president Dana White) then made it into an official physical title for his fight with Jorge Masvidal at UFC 244 in 2019.

Quick Scoop

  • The phrase and concept “Baddest Motherf—er” as a belt started with Nate Diaz after his win over Anthony Pettis at UFC 241, when he publicly called for a “BMF” fight.
  • UFC president Dana White picked up the idea, green‑lit it, and had an actual BMF belt designed and introduced for Diaz vs. Masvidal at UFC 244 in November 2019.
