No doubt some of you will be au fait with downing a pint of beer while your mates in the pub watch on in awe, shouting, 'CHUG! CHUG! CHUG! CHUG!'
But what if it wasn't lager, but milk? And, weirder still, what if it wasn't a pint, but 2.5 litres? Suddenly that glass of Carlsberg doesn't seem quite so impressive, does it?
Well, that's exactly what one Chinese tourist did in Australia, after being stopped by airport security for carrying a huge jug of milk.
Pear Video reports that the bloke, a tourist from Zhengzhou in east China's Henan province, was walking through an Australian airport with a three-litre milk bottle, which had already been partly consumed.
However, when he got to the security checkpoint - the place that puts the fear of God in even the most innocent of travellers - he was stopped by staff, who told him he violated the 100ml hand luggage liquid restriction... and by quite a long way, as he still had 2.5 litres of the stuff left.
That was when the man grabbed the carton and downed all 2.5 litres of milk left in it.

Thankfully, he had a good friend on hand to film the whole thing for us, who told Pear Video on Wednesday that they had simply wanted to buy some milk because it was cheaper to buy it in Australia than their native China.
"It's way cheaper to buy milk in Australia than in China," the man, surnamed Nan, told reporters.
"It's cheaper than getting water there!"
According to the Daily Mail, Aussie supermarkets have been selling milk at AUD $1 (£0.54 / US $0.70) a litre, but milk in China - particularly imported products - can cost up to 60 yuan (£6.84 / US $8.94) per litre, while locally produced milk usually costs around 11 yuan (£1.25 / US $1.63) to 13 yuan (£1.48 / $1.93) a litre
"We were not allowed to bring the milk on the flight, so my friend decided to drink all of it at the airport," Mr Nan said.
"I've never seen him drink so much milk before," he added.

The video footage of the milk lover chugging the good stuff went viral on Chinese social media, where net users compared the clip to a scene in a popular 2010 Chinese comedy film called Lost on Journey - which sees Niu Geng, a man who works as a milk extraction technician decide to down a gallon of milk after being stopped by airport security, only to later need the bathroom repeatedly throughout the flight.
"This is exactly what happened in the movie Lost on Journey!" one person wrote.
"He might regret it once he gets on the plane!" someone else commented.
"Australian milk really does taste better!" a third added.
Dude must really love his milk. Either that or a good bargain, which we can all relate to.
