Colleges can appoint monitors in the locker rooms. These monitors can be students or staff members who are trained to ensure that the environment remains appropriate. They can also be responsible for addressing any issues immediately if they hear any inappropriate stories being spread. Additionally, promoting a strong campus culture of respect and propriety can act as a deterrent to the spread of such stories.
Colleges can enforce strict codes of conduct. Make it clear that any form of inappropriate behavior or story -telling in the locker room or on campus related to such is unacceptable. Punishments for violating this code could include disciplinary actions like suspension or community service.
