During a Saturday concert in Kansas City, Staind frontman Aaron Lewis put his band’s performance on hold to go off on audience members who were allegedly touching a teenage girl inappropriately as she crowd-surfed. The singer’s explosive rant was captured on video.

“Alright, listen up, you f***ing a**holes,” Lewis began after stopping the show in the middle of a song. “That f***ing girl right there is, like, 15 f***ing years old, and you f***ing pieces of s**t are molesting her while she’s on the f***ing crowd.”

He then told the alleged offenders that their mothers “should be ashamed of themselves.”

“You should all be f***ing beaten down by everyone around you for being f***ing pieces of s**t. If I f***ing see that s**t again, I swear to god, I will point you out in the crowd and have everyone around you beat your f***ing a**.”

While it’s never a good idea to encourage violence, it’s unlikely the inappropriate behavior continued after that expletive-ridden tirade.
