Jumping the broom
Jumping the broom (or jumping the besom) is a phrase and custom relating to a wedding ceremony in which the couple jumps over a broom. It is most widespread among African Americans and Black Canadians, popularized during the 1970s by the novel and miniseries Roots, and originated in mid-19th-century antebellum slavery in the United States. The custom is also attested in Irish weddings.
Possibly based on an 18th-century idiomatic synonym for a sham marriage (a marriage of doubtful validity), it was popularized with the introduction of civil marriage in Britain by the Marriage Act 1836. The expression may also derive from the custom of jumping over a besom ("broom" refers to the plant from which the household implement is made) associated with the Romanichal Travellers of the United Kingdom, especially those in Wales.
