The timeperiod between thinking a song or album is so-so, and having it play non-stop on your itunes.
Hilton: Did you hear that leaked Angels and Airwaves cd?
Ian: Yea I did, what did you think of it?
Hilton: It's kind of meh.
Ian: True, but let's let it incubate.
n. a human, usually a woman, whose main function has become the production of offspring, many times with careful consideration and intensive efforts given to ensuring favourable conditions (i.e. cash handouts, preferential parking, tax breaks, health, happiness, etc.) for both producer and offspring during and after the incubabtion period. (2007-d.f. < jenandtaraism orig. in reference vast numbers of ill equipped couples getting pregnant and having plasma screen televisions -oh and a kid, too, ink-yu-babe-er.)
The current cash offer of the government's "baby bonus" has the potential to turn many an impressionable teenager or upwardly mobile welfare mum into a mere incubaber.
"Geez, how many kids does she have now? Seven!?!"
"Wow, she's a total incubaber!"
"Yeah, with the cash the government gave her for the latest one they (un)wisely bought a third motorbike!"
When some resigns or retires from a job, they are on "eternity leave". This can also refer to someone who has passed away, especially someone who worked somewhere for a long time, retired/resigned, then passed away later.
Oh I'm sorry, you didn't know that Kelly is on eternity leave? She resigned and moved to Hawaii!
With regrets I would like to inform you that my boss is officially on eternity leave. I will never see or hear them again. Ever.
