phrase used to express the inability to tolerate the boiling frustration/anger that someone's unbereable personaliby (or actions) brings upon you any longer
-so.... why did you break up with her/him?
-Cuz every day he/she had to start a fucking fight over the most stupid things!;If it was not the way I dressed, then It was the way I talked, or the friends I hanged out with...

- yeah; I just could not hold that dick up my ass any longer! so I ended it
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.
