Euphemism for "go to strip club and grab tits". Used primarily by people who are trying to be sneaky and not admit they're going to strip clubs.
Origin of euphemism was from an asian man who would periodically go with his friends to Montreal(the capital of strip clubs) and when asked why he was going, he'd reply, "play basketball".
me: "So what are you going to Montreal for?"
ak: "We're just going to play basketball."
me: "You're not going to the strip clubs, I hear they're really good."
ak: "Nope, we're going to play basketball."
me: "ok(thinking to myself, yeah right)"
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.
