The act of a young boy cutting a hole in a stuffed toy bear and proceeding to ejaculate inside then defecate on the front of the bear and call it winnienthe pooh, pooh bear, or just pooh.
The young boy was alone in his room one night and pulled a Christopher Robbins. That bear will never be the same again.
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.
