More than one thousand new words and phrases have been added to the Oxford English Dictionary – including moobs and gender fluid.
Words including Westminster bubble, foodie, cheeseball, Bocconcini and fuhgeddaboudit are also now to be included.
First recorded in 1987, gender-fluid is an adjective that identifies a person who doesn’t identify with a single gender.
Moobs has been around since about 2001 and refers to a man who has excess fat on his chest, resulting in a breast-like appearance.
A number of food terms also entered the dictionary for the first time.
As well as foodie and cheeseball, cheese eater and cheese-eating have been added.
Chef de partie and chef de cabinet also made the cut.
Although cheeseball was originally an American colloquialism for someone who was awkward or lacking style, it also describes a deep-fried cheese appetizer.
Bocconcini, an Italian word for a small amount of food, will be another food-related word.
Fuhgeddaboudit, meaning forget about it, is another American slang term, heard around New York, that will now feature in the dictionary.
On the acronym front, YOLO (you only live once) makes an appearance for the first time.
Michael Proffitt, chief Editor of the OED, said the latest update includes more than 1,000 revised and updated entries and around 1,200 new senses.
“This confirms the OED as one of the largest and longest-running language research projects in the world,” he said.
In a previous update, size queen and butt plug were added to the dictionary.
