Kyrgios had been facing Casper Ruud in Rome and the match was in its third and final set.
But the Australian took offence to something from the crowd, and began ranting at an individual in the stands.
It led to Kyrgios throwing his racket and a chair with the 24-year-old then packing up his bags and defaulting the game.
While Kyrgios was storming off court, his opponent Ruud was filmed celebrating the win.
And the Australian reacted to a video of that with a simple tweet.
Alongside the clip of Ruud celebrating, Kyrgios commented: “Hahahahaha”.
He also put two crying with laughter emojis, appearing to make light of the whole incident.
The clip of Ruud celebrating was posted by Ben Rothenberg, who had interviewed controversially interviewed Kyrgios 48 hours previously.
In the frank conversation, Kyrgios had slammed World No 1 Novak Djokovic, saying he will never be as good as Roger Federer.
He said: “We’re talking about a guy who pulled out of the Australian Open one year because it was too hot.
“No matter how many Grand Slams he wins, he will never be the greatest for me.
“Simply because, I’ve played him twice (Kyrgios has won both times) and like, I’m sorry, but if you can’t beat me, you’re not the greatest of all time.
“Because if you like look at my day-to-day routine and how much I train and how much I put in, it’s zero compared to him.
“For me, Federer will always be the greatest of all time. What he has done on all surfaces.
“What Rafa [Nadal] has done is pretty scary. He was won 11 Roland Garros’.
“Djokovic just throws me the wrong way.”
