to take a girls virginity, playing on the slang word for vagina as a "clam": meaning cracking that pussy open and indulging in the inner beauty of the female body.
Jordan- what ever happened with that girl last night?
Mackie- I totally shucked her oyster.
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.
