The act of flapping ones hand vigorously against a vagina for pleasure. Pleasure + flapping = plapping
Tom: Damn that bitch Victoria has a right crusty snatch.
Charlotte: I know I saw her last night in the corner of jerome's getting a good plapping from the DJ!
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.
