Shane Lowry was seen ripping into an on-course marshal during the Sunday Singles of the Ryder Cup at Marco Simone.
As we join the now viral video, Lowry is seen setting up to a tricky chip shot over a bunker from the rough.
The on-course marshal standing nearby to Lowry then says to the crowd: "Stand still don't move please..."
A "shhhhhhh" then appears...
Lowry then turns to the marshal and says: "You're making more f***ing noise than anyone else."
"Sorry," the marshal replies.
"Jesus," Lowry mutters under his breath before trudging up to the green to compose himself for the shot in hand.
WATCH LOWRY UNLOAD ON THE RYDER CUP COURSE MARSHAL:
Lowry went on to secure half a point in his singles match against Jordan Spieth.
The Irishman's match was the last one to reach a full conclusion as Tommy Fleetwood in the penultimate match of the day had already locked up the crucial point to ensure Europe's victory.
Europe went on to share the Sunday Singles 6-6 with USA and it meant the hosts prevailed by five points with a 16.5-11.5 victory.
Lowry secured 1.5 points from a possible three during the week.
He won his Friday Foursomes match alongside Sepp Straka but lost his Saturday match with the Austrian.
Rory McIlroy top scored for the week with a total of 4 points from a possible five.
McIlroy's only loss came in Saturday's controversial finish to his fourbals match against Patrick Cantlay and Wyndham Clark.
The Northern Irishman was fuming with the actions of Cantlay's caddie on the 18th green.
Tensions reached boiling point and it all spilled over into the car park where Lowry was forced to pull McIlroy away and into his car.
But come Sunday night, the European team was celebrating on a bus.
In some of the video posts published by the Ryder Cup Europe account, it would seem like there could be a few sore heads in the morning:

USA have not won a Ryder Cup in Europe since 1993 as their wait continues for another four years at Adare Manor in Ireland.
Eight of the last nine Ryder Cups have now been won by the home team.
But despite this trend, McIlroy revealed in Europe's post Ryder Cup team press conference they intend to change all that in 2025.
McIlroy is adamant Europe will win the Ryder Cup in two years' time at Bethpage Black in New York.
