"Moobs" and "gender-fluid" are among more than 1,000 new words and phrases in the latest edition of the Oxford English Dictionary - along with "Westminster bubble."
Gender-fluid, an adjective first recorded in 1987, now refers to a person who doesn't identify with a single fixed gender.
Moobs is the chiefly British colloquialism, first recorded in 2001, used to describe unusually prominent breasts on a man, typically as a result of excess pectoral fat.
First used in 1998, "Westminster bubble" describes an insular community of politicians, journalists, and civil servants, who appear to be out of touch with the experiences of the wider British public.
A feast of food-related terms have also made the latest update, which includes cheese eater and cheese-eating, chef de partie and chef de cabinet, as well as chefdom - a noun meaning the overall fact, state, or positioning of becoming a chef.
