The Sso was an initiation rite practiced by the Beti of Cameroon in the 19th and early 20th centuries. The participants were young men between 15 and 25 years of age who, by completing the rite, became adults and enjoyed added privileges, such as passage into the land of the ancestors at death. Each boy was sponsored by an esia Sso (Sso father). The sponsor of the rite was a village headman; he was expected to provide food and lodging for guests and to pay for several large feasts during the rite's six-month duration. Other important figures were the zum loa, who revealed past sins that the sponsor had committed and which would be expiated by the rite's completion, and the mfek Sso, who organised and administered the rite.
