The Boston Sea Crab is when a man ejaculates in a woman's anal cavity and the female farts and it comes back out
Gary - "Oh I am about to nut"
Shirley "Not in my ass!"
Gary "OH MY GOD"
Shirley "You came in my ass"
**Shirley Farts and jizz comes out**
Gary "I just gave you the Boston SeaCrab"
A combination of the fluids resulting from both male and female ejaculation. Usually causing a heated debate as to who is going to sleep in the wet patch.
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.
