That's UFC welterweight champ Kamaru Usman reacting to Conor McGregorafter the Irishman suggested the two could fight down the line.
After Kamaru broke Colby Covington's jaw and spirit at UFC 245 on Saturday, Conor tweeted out "145. 155. 170" ... and since he's won belts at 145 and 155, the insinuation is that he wants a crack at Kamaru's title.
So, we asked Kamaru about a possible scrap with McGregor -- and Usman didn't hold back.
"You saw what Khabib did to him," Usman tells TMZ Sports ... "Like, oh my god. It wouldn’t even be fair if I fought Conor."
"Much respect to Conor for what he’s done for this sport and transcended it, but nah, this is not what you want."
"Sit down, little man! Sit down! Learn to walk before you can run because I would hurt that guy."
