A fired-up Billie Joe Armstrong didn’t hold back as he called out a fan during Green Day’s set at a major festival.

Fan-captured TikTok footage shows Green Day’s frontman pausing his performance at Germany’s Hurricane Festival on June 22 to address the disrespectful fan.
In the clip, the 53-year-old pop-punk rocker sings into the mic before handing it over to the audience. Suddenly, he removes his guitar, crouches down, and points and shouts at a fan.
We’re no lip readers, but it sure looks like the “Basket Case” singer said something along the lines of, “I’ll beat your ass. Do you understand me?”
Armstrong then picks up his guitar and continues.
The TikTok caption claimed that the fan was using a water gun to spray Armstrong.
“Billie Joe reacts to person who kept sh00t1ng water on his face with a waterg0n throughout the whole show #greenday #billiejoearmstrong,” the caption reads.
Green Day Fans Roast Concertgoer for Being “Scolded” by Billie Joe Armstrong
In the comments, fans roasted the fan for being scolded by the veteran rocker.
“Imagine being scolded by Billie Joe Armstrong. I’d be embarrassed,” one top comment read. “You can tell he’s a dad,” another fan joked.
However, at least one onlooker was old enough to remember when Armstrong used to throw down with unruly fans.
“90s Billie NEARLY came out there lmao,” they wrote.

Fans may recall Armstrong’s history of clashing with audience members. During Green Day’s Woodstock ’94 set, the performance famously turned into a massive mud fight. After the band finished playing, festival-goers stormed the stage, and a security guard accidentally tackled bassist Mike Dirnt, knocking out several of his teeth.
In December 1997, Armstrong went a step further during a performance at the Fillmore in San Francisco. “Hey, why don’t you come here, you little mohawk motherf—er?” he shouted at a presumably rowdy fan.
“You wanna come up here and fight? I’ll fight you right now. Come on, get up on the stage,” the singer added.
Armstrong threw down his guitar and jumped into the crowd, feet-first, to confront the audience member directly.
However, Armstrong hasn’t had those types of incidents in recent years. Still, just because there’s snow on the roof doesn’t mean there isn’t a fire in that punk rock furnace.
