Note: The video contains strong language.

What can men can do? Although the language and threat of violence may be over the top, Aaron Lewis didn’t stand by and do nothing when he saw a girl being molested as she crowd surfed.

This happened during a concert in Kansas City. Lewis stopped the band’s performance and lost it on audience members who were touching a teenage girl inappropriately as she crowd-surfed. The singer’s explosive rant was captured on video.

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

Never do nothing!
