When a chick gives you her phone number and you discover she is already in your contacts, so you check the previous text message exchange to find that you stopped messaging because she was getting too thirsty for your happily married ass.
Man, I had a major case of deja-vagine last night when a customer gave me her number. Turns out we already met and she got a little thirsty for my liking so I cut her off. Please don't tell my wife, lest I end up in the dog box again.
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.
The hypothetical man (often a sinistercharacter who decided not to go to boot camp) that is doing your girlfriend/wife while you are on deployment overseas.
Ain't no use in goin home,
Jody's got your girl and gone.
Ain't no use in goin back,
Jody's got your Cadillac,
Ain't no use in feeling blue,
Jody's took your checkbook too.
