Is Cambridge considered a posh university?
Cambridge at one time was considered to be a posh university along with Oxford. However both are no longer considered as such.
Posh or push or poosh, meaning fashionable or splendid appears in Cambridge University slang in 1903 when P.G. Wodehouse writes of a brightly colored waistcoat that it is "quite the most push thing around." The derivation from "Port Out Starboard Home" is fanciful. Partridge prefers to derive posh from a contraction of "'polished."
