It can basically mean both good or bad depending on the way you use it. it's like saying gay if it's "bad" without using that word. Or if your friend has a new game or hot shirt from a band with it's signature can be called "sicktits".
It was basically made when someone slurred the words "sicko" and "attitude" together.

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.
