A disparaging term used to refer to a certain clique of north London,
white, liberal, middle-aged mothers. They can be seen frequenting Gail's, Hampstead Heath, brunch, and attending yoga and pilates. They are known to be 'right-on'- meaning they empathise with their children on issues such as inequality and climate
change, while simultaneously driving an oversized 4x4 to drop little
Tom and Eva off every morning at their £20,000 a year private school.
