Anthony Joshua has finally snapped - and you can hardly blame him.
Usually so mild-mannered and humble in the public eye, the 29-year-old couldn't contain himself any longer on Thursday following jibes from Deontay Wilder, Joseph Parker and Tyson Fury.
Everyone wants a piece of the IBF, WBA and IBO heavyweight champion at the moment as speculation of his next opponent continues to swirl.
He recently defeated Carlos Takam to record his 20th career victory - all of which by knock out - and extend his unbeaten run.
His promoter, Eddie Hearn, revealed on Wednesday that talks were underway over fights with Parker and Wilder.
Hearn then confirmed on Thursday that Joshua will face Wilder in 2018, while Fury is still in the picture providing he can get fit and obtain a boxing licence.
But Joshua has had enough. In a Twitter rampage, AJ called out Parker and Wilder before brutally labelling Fury a "fat f***".
In three separate tweets, he wrote: "@joeboxerparker Sips tea, continues to read tweets & refreshes email... Still no offer.
"A little word on the @BronzeBomber (Wilder) fight. Ready & waiting for the offer.
"@Tyson_Fury get fit you fat f***."
The saying goes 'killing two birds with one stone', but Joshua decided to take on the trio with three tweets in the space of an hour.
Swearing isn't usually Joshua's style, which prompted iFL TV presenter Kugan Cassius to get involved by joking that the 'real Anthony Joshua' has finally revealed itself.
AJ was having none of it, though. He quickly hit back at Cassius with a savage response telling him to "shut the f*** up".
And when Cassius tried to antagonise AJ further, the Brit lashed out again.
The beast has awoken. Joshua is admired by boxing fans for how calm and level-headed he is, but there's only so much a man can take.
He will now have his eyes on taking down Parker, Wilder and Fury to shut them up, perhaps starting with Wilder in the new year.
"Deontay Wilder is doing a great job of convincing people that AJ is running from this fight," said Hearn on Thursday. "Our job to deliver but it doesn't happen overnight.
"This first meeting today may go well, it may go terribly, but fans need to know we want the fight. It will happen in 2018 unquestionably."
