The term Sloane Ranger (often shortened to Sloane or less frequently Sloanie) refers to a stereotype in the UK of young, upper class or upper-middle-class women, or men who share distinctive and common lifestyle traits. The term is a punning portmanteau of "Sloane Square", a location in Chelsea, London famed for the wealth of residents and frequenters, and the television Westerns character The Lone Ranger.
Initially the term "Sloane Ranger" was used mostly in reference to women, a particular archetype being Diana, Princess of Wales. However, the term now usually includes men. Male Sloanes have also been referred to as "Rahs" and "Hooray Henrys". The term Sloane Ranger has similar related terms in other countries: in France they are called 'BCBG' (bon chic, bon genre).
