Billie Joe Armstrong of Green Day almost lost his shit at Germany’s Hurricane Festival this past weekend when a fan wouldn’t stop squirting him with a squirt gun.

At first, Armstrong flipped the fan off and pointed them out in the crowd — but things escalated fast. He ripped off his guitar and stormed to the front of the stage like a furious parent shouting at a PTA meeting, finger-pointing and all.

It was giving "mom just found out you carved your name into the coffee table" energy. Check out the footage in the TikTok video below.
