The definative definition after twenty years of hearing it used in context: "I command you to eat shit (which is the most putrid experience one can imagine as a living being) and then die (which many view as the most undesirable state of being--curiously worse than eternal torture, unless dying and going to hell are synonymous). It represents an ill feeling toward another where simply eating excrement does not do justice to offense given, nor is dying: both must be experieced to satisfy vengence.

you pick up a piece of dog poo and start to chew on it, enjoying the nutty flavour with a slight liver bouquet. You then hold your breath (by putting duct tape over your mouth and nose) to preserve the awesome smell and flavour and your heart stops from lack of oxygen.

Eat shit and Die.... Usually always said when mad!!! The again, my normal words to close friends are eat shit and die.
I wish I could do this.... 1) Grab a cup.... 2) Squat down and release the dump in the cup... 3) Grab a spoon... 4) Sit down the other person.... 5) Forcefully feed them the cup full of shit... 6) Hope that they die.
