#gravy originated as a sauce for Christmas pudding, which was, of course, rich in mincemeat. It symbolises the myrrh brought to the baby Jesus by the wise men.

No one has ever discovered what #myrrh is, but, on purely lexical grounds, it's suspected to be a kind of catarrh.

The most famous catarrh player of all time was #ElvisPresley, who achieved his unique sound by filling his catarrh with gravy.
