London (PTI): It's a defining moment for the humble custard cream -- the crispy, mouth-watering biscuit has finally made it into the latest edition of the Oxford English dictionary.

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.
