10. Marilyn Manson

Marilyn Manson is known for some of the wildest moments in rock history, and his actions on social media show that side clearly. In 2001, during a concert, he shocked the crowd by grabbing a security guard, wrapping his legs around the man’s head, and rubbing himself against him while wearing only pantyhose and a leather thong. This caused legal trouble and fines.
He also made headlines by dragging a meat cleaver across his arm during a show, dedicating the act to Paris Jackson, who was going through a tough time.
