The term "kwaussie" - a hybrid of Kiwi and Aussie - has been named Australia's word of the year.
The portmanteau came to prominence in 2017 through the nation's dual citizenship political saga, said the Australian National Dictionary Centre.
It describes a person who is a dual citizen of Australia and New Zealand - as was the case with Australia's deputy prime minister, Barnaby Joyce.
Mr Joyce was removed from office in October for being a kwaussie.
He won back his seat in a by-election on Saturday after renouncing his New Zealand citizenship. Under Australia's constitution, politicians cannot be dual citizens.
"Kwaussie was used to describe the most high-profile casualty of the crisis, deputy prime minister and National Party leader Barnaby Joyce," said Dr Amanda Laugesen, the dictionary centre director.
"In a time of covfefe, fake news, and tweetstorms, the Australian National Dictionary Centre has looked for a word of the year that is both lexically interesting and Australian."
Although popularised by the political saga, the word can also refer to a New Zealander living in Australia, or a person of Australian and New Zealand descent, she said.
Friendly rivalry between Australia and New Zealand has often led to minor quibbles over claims to famous citizens.
