[1] The term "rah" originated as a contraction of "Hoorah Henry" (sometimes "Hoorah Henries and Henriettas"), a pejorative description of a social stereotype similar to the Sloane Ranger stereotype also recognised in the UK, though a rah is generally younger, typically around university age (18–25), and less associated geographically with London.
The use of the term is likely to have been furthered by onomatopoeic correlation with the way in which those fitting the stereotype are perceived to talk, with the word 'rah' being associated with upper-middle class affluence since at least the early 1980s.
[3] The use of the term 'yah', similarly, is likely to have been furthered by a perceived and much-parodied upper-class pronunciation of the word 'year' in the phrase 'gap year'.
For girls, pashminas, jodhpurs, Ugg boots, flares and cable-knit jumpers combined with scruffy hair arranged in a bun or drastic side partings are common.
In colder seasons, country attire and outdoor wear is popular, especially brands such as Hunter Boot and J. Barbour & Sons.
