Staind was performing at Rockfest in Kansas City on Saturday afternoon when front-man Aaron Lewis noticed something in the crowd.

It appeared that young, female crowd surfer was getting abused.  Lewis stopped the song they were performing, Something To Remind You, and launched into a profanity-laced tirade against the abusers in the crowd.

The language is NSFW

Lewis ranted:

"Alright, listen up, you fucking assholes. That fucking girl right there is, like, 15 fucking years old and you fucking pieces of shit are molesting her while she's on the fucking crowd. Your fucking mothers should be ashamed of themselves, you pieces of shit. You should all be fucking beaten down by everyone around you for being fucking pieces of shit. If I fucking see that shit again, I swear to God, I will point you out in the crowd and have everyone around you beat your fucking ass."

The video isn't great, but you can hear the NSFW audio.
