Order of Isis
Mostly used in the American Midwest, an 'Order of Isis' is a slang term for 'two eggs and a glass of water'. For instance, if a waitress at a Truck Stop were to shout back to the cook this common phrase:
Gimme an Order of Isis, ground and Hojo!
That would mean
"I have an order for two eggs, a glass of ice water, a cup of coffee and a beating heart freshly cut from a live clown!"
