The Dorset Ooser (/ˈoʊsər/) is a wooden head that featured in the nineteenth-century folk culture of Melbury Osmond, a village in the southwestern English county of Dorset. The head was hollow, thus perhaps serving as a mask, and included a humanoid face with horns, a beard, and a hinged jaw which allowed the mouth to open and close. Although sometimes used to scare people during practical jokes, its main recorded purpose was as part of a local variant of the charivari custom known as "skimity riding" or "rough music", in which it was used to humiliate those who were deemed to have behaved in an immoral manner.
