Southern Ontario rural-ism, meaning, she is dumber than a dog... The longer version of the phrase, which is seldom spoken, is "She don't know sick'em from fetch!"

When your problems,especially your love-life, get too much for you and you, unexpectedly, 'throw-up' all the stuff going on in your life and through your mind over a friend (a third party). Neither of you expected it to happen and at least you feel better for it afterwards though your friend often wonders what they had done! Probably made the mistake of asking "What's Up?". Usually easier to do thru email or text as they can't stop the onslaught!
I think Annie's love-life has all got too much for her, Jane's just told me she was emotionally sick all over her when they met.
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.
