This long weekend, some people might be going to a bush doof, perhaps while wearing hobo gloves.
Others might instead choose to spend time in their fibro majestic doing a spot of social reading.
If you're not sure what that means, then you might need to pick up the latest edition of the Macquarie Dictionary, which includes these and 5500 other new words and phrases.
For the record, a bush doof is an outdoor dance party held in a remote location and hobo gloves are gloves with no fingertips.
As for fibro majestic, that's the humble fibro home and social reading is reading an ebook through a social network and communicating with fellow readers.
Susan Butler has been involved in editing all six editions of the Macquarie - the first in 1981 and the latest released this month.
She said new words came from a range of areas, including fashion, colloquialism, health and politics. The big mover in word creation - and proliferation - is the field of computers and the internet.
"Computers, internet, technology are all very productive."
The internet, particularly through social media outlets like Facebook and Twitter, has also substantially quickened the pace at which we adopt new words.
"Any word that's launched into the world these days, such as fiscal cliff, it only takes moments now for a word like that to travel around the world and be explained," Ms Butler said.
"In the 1980s, I'd allowed a 10-year lag for things to turn up in Australian English, having turned up in American English," Ms Butler said.
"Now, I think, it's just a matter of minutes."
