Erotic wrestling
Erotic wrestling is a kind of wrestling, done by women or men, usually as a show, like at the Burning Man. When they do it, these Wrestlers are often covered in oil,  and they wear very little clothing (or they are completely naked).  It often is part of adult entertainment. Even though they are often also covered in oil, this has nothing to do with oil wrestling, which is done by clothed men, as a sport.
