Luke Bryan drank a beer while on stage in Australia, but it's how he drank it that has us cringing, and maybe vomiting.

Did you know a "shoey" was a thing? Per the internet, it's popular in Australia, and that piece of trivia is backed up by the woman in this video of Bryan doing a shoey who screams "He's doing a shoey! Wooooo!!!"

A shoey is when you drink beer out of a shoe, or in this case a cowboy boot. It's not clear where the boot came from or whose foot it was on all night prior to Bryan taking a sip and spilling the rest of his beers all over his shirt and guitar.

Brothers Osborne also did a shoey at CMC Rocks in Sydney, Australia. A photo shows John Osborne really getting into it, sacrificing what looks to be an expensive designer boot. There's a chant that seems to go along with the ritual, but we couldn't make out the words.

CMC Rocks is a massive music festival in Australia that features artists from around the world. Darius Rucker, Kelsea Ballerini, Old Dominion and Dustin Lynch are a few more American acts on the lineup. It runs through March 18.

Bryan will play shows in Australia through March 20, then do a few one-off shows before beginning his What Makes You Country Tour on May 31 in Toronto. The stadium portion of that tour will feature Sam Hunt as an opening act. He has tour dates scheduled through October, with a break in the spring for him to appear as a judge during live episodes of American Idol.
