Australian Olympic hero Ariarne Titmus' swim coach has gone viral all around the world for his priceless outburst following her historic gold medal - but not everyone enjoyed his antics.
Titmus, 20, stormed home to win gold in the 400m freestyle over America's greatest ever female swimmer Katie Ledecky on Monday, with her coach Dean Boxall's crazy celebrations being broadcast across the globe.
Boxall ripped his face mask off and started running up and down the stands before screaming and gyrating as a staff member panicked in the background.
His euphoric behaviour wasn't enjoyed by everyone however, with a number of Americans taking to social media to label Boxall 'vulgar and frankly offensive'.
'What the Australia coach did isn't funny or cute. It bigfoots a woman athlete winning a gold medal and centers the attention on him,' an American author named Laura Chapin tweeted.
'It's vulgar and frankly offensive and he should apologise to her and everyone else.'
Boxall refused to apologise for the celebration, saying his only regret was breaking Japan's strict Olympic Covid protocols by ripping off his mask.
'I lost it. I think I went outside my body. I just lost it. That's a moment of being with this girl for five years and having a dream together,' Boxall said.
'The Americans might not like it, I don't know. But I bleed with my athletes.'

Boxall, who Titmus and her family relocated from Tasmania to Queensland for him to be the prodigy's coach, was caught on cameras of broadcasts around the world stalking the pool as the 20-year-old approached the wall for her first gold medal.
'I mean he is going crazy. Oh my goodness, haha! He's like putting on a show like Mick Jagger and the Rolling Stones or something,' the commentator said as he burst through barriers and threw his mask.
Boxall then grabbed onto a glass barrier and shook it vociferously as he gyrated into the railing.
He then punched the air and screamed at the pool as a startled Japanese Olympic worker nervously tried to encourage him back into his section.
The coach was later overcome with emotion and wiped away tears while Titmus took to the podium to accept her gold medal.
Despite millions around the world praising the coach for his charming and raw reaction to the win, some critics accused him of displaying 'toxic' behaviour.
'That Australian swim coach is toxic as f*ck and I hope these athletes don't have to deal with him too much longer,' one woman tweeted.
'There's no way he's not building unsafe relationships. With all we know about athlete mental health, especially Olympic athletes, it's extra disgusting,' she added.
Titmus and his other swimmers have repeatedly praised Boxall's energy and personality, as evident by Titmus' family uprooting themselves from Tasmania so he could coach their daughter.
'He means everything to me,' Titmus said of Boxall.
'There's a lot of different ways of showing emotion and how proud you are and Dean's obviously quite expressive. For me, at this point in my career, I think it's really important because his energy certainly lifts me up,' fellow Olympian Mitch Larkins added.
'There is such a great relationship between Dean Boxall and Ariarne. That is what emotion is all about,' Titmus' father said of his daugher's coach.
Despite his charming and raw emotions, Americans unsurprisingly found a way to get upset, with one calling him 'toxic'
