Tyson Fury has threatened to slap Andy Ruiz Jr in a brutal verbal assault on the heavyweight world champion.
Fury, who beat Tom Schwarz last month, is set to return to action in October and ahead of his heavyweight contest, he's taken aim at Ruiz Jr.
"Lil fat f***er! So, if he [Andy Ruiz Jr] wants a slap too, he can have one too," he said to Michelle Joy Phelps on Behind The Gloves.
"Andy Ruiz if you want a slap, you can have one in all. Cause I ain't bothered about you fatso.
"I'll hit him in the body make him spew marshmallows for a month," he added.
It's not the first time Fury has thrown shade at Ruiz Jr. The lineal heavyweight champion called the Mexican-American a "bum" despite dethroning Anthony Joshua.
"Yeah, Andy Ruiz is a bum, everyone's a bum. I'm still a fan of the guy. I don't know if people want me to talk bad about him, but that's not the type of guy that I am," the unified king said.
"As long as he does what he has to do, I salute Tyson Fury. And Wilder too you know because it takes a lot for us big guys risking our lives inside the ring to take care of our families.
"I'm not the type of guy to talk outside of the ring. But inside the ring, I'll be doing all the talking for sure."
The 29-year-old has refused to take his eye off Joshua. "First I want to focus on the rematch," he added.
"You know a lot of people, and I'm speaking to Joshua too, because he was overlooking me and saying. 'After I beat Andy, I'm going to fight Wilder' and this and that, instead of being focused on me.
"I think that's what I want to do right now, just focus on the rematch. I don't care who I'm going to fight next after I win, the main thing right now is just to fight Anthony Joshua and beat him."
Ruiz Jr will rematch Anthony Joshua later this year while Fury has eyed up Trevor Bryan as his next fight before facing Deontay Wilder in February 2020.
