When someone works your sacklike a punching bag, but with their feet, while you piss in their face (displaying the spurts of water that accompany paddle boating)
"Dude, you think the Dutch Rudder kicks ass?? Wait till some chick gives you the Paddle Boat... with cashmere socks on."
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.
