While no competition or criteria to determine the ugliest man in the world exists, the winner of Zimbabwe's annual ugliest man competition, such as 2015 winner Maison Sere, might make a claim to the title. Another potential claimant is the self proclaimed ugliest man in Uganda, Godfrey Baguma.
Previous winners of Zimbabwe's contest include three-time winner William Vasinu. The competition began in 2012.
Baguma, who suffers from a rare medical condition that resulted in a deformed face, makes public appearances as the ugliest man in Uganda.
In general, physical attractiveness, which encompasses both ugliness and beauty, is extremely subjective and varies depending on individual and cultural tastes, as well as time period.
