THE Northern Territory's mischievous mankini golfer is now facing legal trouble, one of his best mates said.

The scantily-clad man turned heads when he played a round at the RAAF Darwin Golf Club wearing just the green togs and golf shoes while swigging a stubbie.

His cheeky antics have angered RAAF bosses, The Northern Territory News reports.

While police told The NT News no formal complaint had been lodged just yet, many outraged Territorians have been threatening to press charges.

NT News facebook followers were far from impressed with the golfing chap's antics.

"He should be charged ... indecent exposure," said Raechel Watts.

Debbie Neat said the man's dress code was "totally disrespectful of the game".

"How disgusting! He should not have been allowed to play without proper attire!" said Jennifer Fitzgibbins.

"Whoever said golf was a gentleman's game has not been to this place."

But others, including Julie Pannell, commended the brazen act.

"Haha good on him, so damn hot in the NT," she said.

Rachael Beier Gotta said: "Gotta love a man in a mankini, those tan lines are a bugger though.

The mankini went viral when British comedian Sacha Baron Cohen broke it out in the 2006 comedy Borat - his first mockumentary, about a man from Kazakhstan who journeys across the United States in an ice cream truck - in 2006.
