Yes, really. Even though its two words. Go figure.
From the Australian National Dictionary Centre, based at the Australian National University.
Centre director Dr Amanda Laugesen said the official definition was "a barbecued sausage served on a slice of bread, bought at a polling booth sausage sizzle on election day".
- She said the term was first recorded in 2012, but its use increased significantly during the federal election this year, especially with the popularity of several websites set up to help voters find polling stations with sausage sizzles.
