Accompanying the Provo Soak (Mormons have strict guidelines from their church prohibiting any sexual tenancies before marriage, the Provo soak is where the girl will allow her boyfriend to stick his boner into her vagina and not move, thinking this does not count as sex) the couple will have another person jump on the bed/couch to move them so that they aren't the ones creating movement, meaning they're not having sex. Only a select few Mormons think this isn't sex, and this is mostly Mormon myth.
