A new internet site which invites people to send in everyday expressions which have yet to make it into the dictionary has opened for business.
Suggestions could become new dictionary entries
The "living dictionary" has been started by lexicographer Collins to keep track of newly-emerging English words and phrases.
If a word has enough submissions and a definition can be agreed, it could make it into the hardback edition.
Early suggestions include adultescent, a grown-up clinging onto youth.
Other new phrases being considered are mucus trooper - a person who comes into work despite being unwell.
Jeremy Butterfield, the editor-in-chief of Collins Dictionaries, said it was important to bring commonly-used words into the official langauge.
"We felt it crucial to reflect language that is really used," he said.
"One of the key ideas is to get real language-users actively involved in getting words into the dictionary," added Mr Butterfield.
Phrases which were included in the most recent edition of the Oxford Concise English Dictionary included va-va-voom, speed dating and flash mob.
