The #YesAllWomen hashtag has been used to remind people of the everyday sexism and harassment that women face all the time, and that includes concert.
Over the weekend, Staind was performing at the Rockfest festival in Kansas City, Missouri when singer Aaron Lewis noticed that a female crowdsurfer was being "molested" by men in the audience.
Lewis, a father of three girls, stopped the concert and blasted the offending men in no uncertain NSFW terms.
"All right, 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 is on the fucking crowd. Your fucking mothers should be ashamed of themselves, you pieces of shit."
After threatening to have the tables turned if he saw such behaviour again -- "I will point you out in the crowd and have everyone around you beat your fucking ass" -- he then said, "Now girls, feel free to crowdsurf safely" and got back to business.
But this isn't a problem that just happens to fans. Iggy Azalea recently revealed that she had to stop crowdsurfing because she was being sexually assaulted by her own audience.
