chattering classes

(UK, informal, archaic) A talkative person; chatterbox.

(humorous, chiefly, UK) , favoured by upper-class British citizens.

British slang for a female chav — a term applied (usually pejoratively) to a young working-class woman associated with sportswear brands, big hoop earrings, a particular dialect, and a certain attitude. Like 'chav,' the word carries strong class-based judgment and is considered by many to be a classist slur, though it's also been partially reclaimed by some as a badge of pride. You'll find it in British tabloids, reality TV commentary, and increasingly in academic discussions of class in the UK.

Chatter; prattle.

(colloquial) Mindless and irrelevant chatter.
