An idiot. Originated when a person was annoying their friend in maths class so said friend wrote a note to said annoyer. The note was meant to say "Shut the hell up" but the friend's writing was so bad that the annoyer took the note as saying "Shut the hollup". Therefore the only two people who knew about this new word was the annoyer and the annoyee. It then bacame tradition for the annoyer to tell friends of the annoyee to tell the annoyee that she/he is a hollup, or vice versa. Fun for all the family.
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.
