"I am going to f**king butcher you"
That's a fired up Conor McGregor making some serious threats to Justin Gaethje -- telling the UFC's interim lightweight champ that he's coming for Gaethje's head.
"Your teeth. I’m going to put them on a f**king necklace," Conor said to Justin.
In an angry Twitter rant Monday, McGregor says he wants to fight Justin next -- and it seems the hostility comes from a 2019 tweet Justin sent criticizing Conor as a "sh*t human, father and husband."
