A SpadeBunny is a female of any race that will only have sexual intercourse with Black Guys. The Name comes from the combination of "QueenOfSpades" (A woman that's exclusive to Black Men for sex) and "SnowBunny" (White female that only fucks Black Men).
WhiteBoy1: I have a crush on a girl but haven't made a move. What should I do?
WhiteBoy2: Just give up dude! I've seen her past boyfriends, she's a SpadeBunny!
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.
