Modeled on the exclusive Oxford dining club Bullingdon--which famous conservative British politicians David Cameron, Boris Johnson, and George Osborne belonged to-- Posh is about ten young, privileged men who are members of the Riot Club, and have plans for a night of eating, drinking, carousing, and smashing property, resonant of Bullingdon Club's rowdy antics. More than peering into the world of upper class young men who have a sense of superiority and self-entitlement, this play does a brilliant job of accurately capturing speech, mannerisms, and other finely nuanced textures of posh sub-culture.
