A Sloane Ranger is someone who is like a posh princess or prince. They live in fancy neighborhoods in London called Chelsea and Kensington, have lots of money, and wear very preppy clothes like polo shirts and blazers. They are often seen hanging out at exclusive clubs or having tea at nice hotels. The term came from a magazine article in the 1980s that described this type of person. The Sloane Ranger is known for being well-educated and having good manners, but sometimes they can be a bit snobbish or stuck-up.
