Literary experts included the popular vanilla-filled snack after nine out of ten people in the United Kingdom voted it their top biscuit in a survey.
"Noun. Biscuit with vanilla-flavoured cream filling," reads its definition in the dictionary.
The treat, invented 100 years ago, features alongside new words such as ‘muffin top: a roll of fat above the top of a pair of women's tight-fitting, low-waisted trousers," The Sun has reported.
The dictionary also sees ‘car crash’ and ‘train wreck’ make their debut -- describing disastrous events that hold ghoulish fascination.
Meanwhile, if someone's described as ‘neet’ they may not be smartly dressed -- it's a young person who is not in education, employment or training.
