It is the latest craze to sweep the nation - and now it has come to the streets of Shropshire.
'Neknomination' has taken off on social media website Facebook and sees someone post a video of themselves drinking an alcoholic drink in one - and then nominating a friend to do the same.
The craze has been criticised by health campaigners and nationally two people are said to have died taking part, including 19-year-old Jonny Byrne from Northern Ireland.
Mr Byrne's family said he died after jumping into the River Barrow in Carlow on Saturday after taking part in the craze.
Now the controversial trend has arrived in Shropshire in this video, posted to YouTube and showing Andrew Thomas walking down Pride Hill in Shrewsbury wearing only underpants, socks and a rugby helmet and boots.
Carrying a pint of Guinness and a rugby ball, Mr Thomas turns to the camera and says: "People of Shrewsbury, if I could have your attention please. Dai Roberts thank you very much for my neck nomination, here it is."
Mr Thomas then drinks the pint in one, before turning back to the camera and saying: "I'd like to nominate Alan Roberts and Dean Pritchard, you have 24 hours, good luck. People of Shrewsbury, enjoy the Six Nations."
He then carries on walking down Pride Hill singing Welsh rugby anthem Hymns and Arias by Max Boyce.
Mr Thomas said: "Good innocent fun I say. But I would think that. Can't say agree with necking pints of Vodka etc as it can get dangerous but nothing wrong with a beer and a bit of semi nakedness."
The video finishes with a selection of tourist-style snaps showing Mr Thomas next to The Quantum Leap statue and The Shrewsbury Hotel.
