TROLL king Daniil Medvedev slammed the 'stupid' Australian Open fans for doing the Cristiano Ronaldo celebration.
And then he brilliantly signed the TV camera 'siuuu' in an extra swipe at the annoying Aussie crowd.
The Russian star, 25, was frustrated by the Rod Laver Arena's constant use of the boo-like noise during his blockbuster showdown with Nick Kyrgios.
After wrapping up a 7-6 6-4 4-6 6-2 win, Medvedev told 1992 and 1993 champ Jim Courier on court: "I came to win this match and I am happy that I managed to do it. That's the only choice when you are booed between first and second serves."
When they carried on, No2 seed and Australian Open favourite Medvedev continued: "Guys, I can't hear him. Please, show some respect for Jim Courier. He won here. Thank you.
"On the games I lost on the break points - it's tough to play."
The US Open winner added to Eurosport: "It's just a little disappointing when they are making so much noise between first and second serves, I guess some people just have a low IQ."
But before leaving the court, Medvedev could not resist one final dig as he was handed the pen to write on the lens.

Unlike Andy Murray on Tuesday, Medvedev knew all along what the noises were.
After all, he is a massive football fan - famously crowning his Flushing Meadows victory by flopping to the floor to recreate a FIFA celebration.
But it was a solid and albeit unspectacular win from Medvedev in round two as he continued his charge towards back-to-back majors, despite the distractions on the other side of the net.
Kyrgios beat Brit Liam Broady with an underarm tweener serve and he was up to his usual tricks once more on the main show court at Melbourne Park.
But after the sheer entertainment show in round one, it was more drama this time around with a combination of sublime and ridiculous in equal measure.
For every opponent's towel cheekily stolen and attempted hot dog there was a moment of madness and a sweaty Kyrgios losing his cool, too.
NICK-ERS IN A TWIST
He was warned early on about his time keeping, pushing the 25-second limit by trudging to get his towel.
An argument with the chair umpire followed, with Kyrgios getting the last words: "No one cares what you say."
The former world No13 came out for the next game by sprinting up to the baseline, clearly mocking Carlos Bernades.
A lap of honour on his way to a crucial break in the third set, set up by a magnificent reflex volley and sealed with a scintillating forehand winner, had the crowd on their feet once more.

But Medvedev held for 5-2 in the fourth and Kyrgios' anger boiled over, obliterating his racket by throwing it to the floor.
That earned him a docked point, meaning he served to stay in the match from 0-15 down and went wide on match point to bow out of his home Grand Slam.
