The tradition of a same-sex group gathering for the purpose of showering together. Usually the activity takes place with the most intimate of friends who are comfortable enough to bond in nude. The activity generally celebrates positive themes of group friendship, such as ethnic diversity or similar taste in music, and can last from fifteen minutes to an hour, depending on the slowest person to "finish". (originates from the state Washington, United States)
