It seems complete and utter chaos is what you get when you combine the world's biggest boyband with one of the world's most popular burger chains.
That was the experience of several Indonesian branches of McDonald's, which found themselves so swamped with demand for the newly launched BTS Meal they had to close.
BBC News reports so many people ordered the meal inspired by the Korean boyband that there were fears it could cause a new Covid hotspot.
If you don't follow BTS, this may all seem a bit of an overreaction to a meal consisting of 10 chicken nuggets, fries, a coke and two sauces.
BTS's last single Butter broke global records when it premiered last month while they beat superstars like Taylor Swift to be named the best-selling album of 2020.
The band formed in 2013, and have gone from strength to strength.
Their fans – and there are millions around the world - are exceedingly loyal, and protective.
BBC News reports using their brand in the wrong way can mean trouble, as one South Korean MP found out this week.
Ryu Ho-jeong, the country's youngest MP, used an image of tattooed BTS member Jungkook to make a point about easing restrictions on tattooing.
South Korean laws mean only doctors are allowed to do tattoos.
But fans were angry she had used the picture, saying she had dragged the star into politics.
She later apologised after facing widespread criticism on social media.
But when fans approve of the partnership, like the one with McDonald's currently being rolled out to 49 countries, it can mean massive success.
BBC News reports Police in Jakarta said in a statement that a total of 32 branches were temporarily closed across the city.
There were further closures in other parts of the country.
