WBC heavyweight champion Fury is currently in negotiations with Joshua over an all-British title fight later this year.
The pair have reportedly agreed terms to face each other on December 3 at Cardiff's Millennium Stadium.
There is believed to be a 60/40 split in favour of the title holder, with the split moving to 50/50 in a rematch if Joshua wins.
Fury's team claim to have sent the contracts over to Joshua last week but the fight is yet to be fully confirmed.
Fury, who is currently on a meet and greet tour around the UK, got thousands of his fans to direct a chant at Joshua on Friday, urging him to hurry up and sign the contract.
"AJ sign the contract, AJ sign the contract," Fury encouraged fans to sing during the tour's stop off in Poole, Dorset.
He then followed it up with: "AJ is a p***y, AJ is a p***y."
Fury ended by singing: "If he doesn’t sign the contract now, we all know he's a s***house."
Fury has also directed insults at WBA, WBO and IBF heavyweight champion Oleksandr Usyk, who beat Joshua via split decision in their rematch in August to retain his titles.
After Usyk had suggested Fury was scared of facing him, the 'Gypsy King' fired back on Instagram: "Usyk, you little s***house, you little s***bag.
"Talking s***e! I'm afraid of you? I'll put my fist right through the side of you, you little sausage. And the other s***house, that big bodybuilder Joshua, that's a proper s***house.
"Had the contract for I don't know how long and ain't signing it. You little sausage, you do not wanna fight, your manager's a sausage.
"I've never seen anything like yous, both a pack of s***houses.
However, I will be fighting December 3 if this sausage does not sign the contract, which I don't think he is because I don't think he's got the b****cks to, because he's a s***bag.
"Both of yous, a pair of little sausage s***houses. Joshua is a s***house, Usyk a s***house. Yous are all s***houses."
Fury's promoter Frank Warren revealed on Friday that the contracts for the Joshua fight were yet to be signed, while AJ's promoter Eddie Hearn confirmed he was still in the process of negotiating certain parts of the agreement.
"It's not unusual to get a contract that you're not over the moon with - and it wasn't that they were playing games or anything like that," Hearn told iD Boxing.
"It's just really down to the format of the agreement, which is being rectified and we're working positively to try and get that in the right shape and I think we're nearly there in terms of the format of that agreement.
"[The contract] wasn't really as we expected, but that was a few days ago and we've had some positive conversations. Reshaping that slightly, which seems to be positive."
