Mummy porn, legbomb and broga also make the cut as online dictionary lexicographers select a word for every month
Consulting editor Ian Brookes said: "Choosing just one word for 2012 didn't match the pace at which our language is changing, so we selected one popular word to represent each month from the whole range of those submitted."
Collins' choices range from January's "broga" – a new form of yoga specifically for men, or "bros" – to December's "fiscal cliff".
Following choices of "Eurogeddon", "Zuckered" – used after the plummet in share price that followed Facebook's initial public offering, but rejected for inclusion in the dictionary – and "jubilympics", is November's pick of "Gangnam style".
The picks came from among almost 7,400 new word submissions from the general public, after Collins opened its online dictionary up to suggestions in recognition of "how language is constantly evolving through pop culture, events and trends". Not all will "have the longevity" to be included in the print dictionary, said the publisher, "but their submission to CollinsDictionary.com shows how the site has become a forum to discuss the new words we use to describe current events and trends".
