MAHMOUD CHARR has branded Tyson Fury a "big giraffe" for going back on his vow to fight him and continuing talks with Anthony Joshua.
The Lebanese-born German moved into pole position to fight Fury this week after Joshua missed the WBC heavyweight champion's deadline to make their Battle of Britain.
But talks over a shock December domestic dust-up are still ongoing, much to the annoyance of Charr.
The former WBA (regular) heavyweight champion told Sky Sports: "Mr Big Giraffe, where is the paper? You didn't sign [it].
"You make the same play like Anthony Joshua, I can't understand it
"Yesterday, you shot your mouth very big and said you want to fight two guys in one night.
"But I told you from you I need five in the night, no problem. Send the paper and make the fight happen because my promoter called me and said Frank Warren doesn't respond.
"Are you scared? Scared, boy? You little big dosser, send the paper."
Charr's latest dig at Fury came after he praised The Gypsy King with a throwback photo of them posing.
He wrote: "Great respect @Tyson Fury. For your fighter's sake, you have proven to many people that you have a strong character.

"A will can move mountains. On our fight night and after my victory, I don't want to hear any excuses."
Charr, 37, has repeatedly vowed to end Fury's reign as WBC king this week, saying: "The lumberjack is coming for you, Habibi.
"Focus on the belt, focus on the belt. You big dosser!"
He added: "Fury, you are the s**t as Anthony Joshua. A man is a man. When you say Joshua is out, he is out.
"You told everyone you want to fight me [and] now we are like a duck. Take the fight."
Fury, 34, performed a U-turn on his Monday deadline to AJ on Thursday, saying: "My promoter Frank Warren convinced me to let Queensberry carry on negotiating with your team this week, despite me knowing that you were never going to do this fight.

"So the deadline was Monday. "I allowed Frank to continue doing meetings with your team and your broadcasters and all that.
"Now we have BT, DAZN and ESPN all on the same page. They are happy with everything, they are all ready to rock and roll.
"You guys ask for a lot of stuff, you want to be co-promoters when you're a voluntary challenger.
"Guess what, I said give it them, let them be co-promoters.
"You wanted full transparency, even though you're not an equal shareholder in this party. You know what I said?
"Give them full transparency, I've got nothing to hide, I'm not trying to rob anybody, I've not robbed anybody of a penny in my life.
"So now you've got full transparency, everything is clean and fair. Now Joshua, the ball is really in your court son."
