Haggis is a dish served on a long plate. It inserts sheeps' lungs, organs, and spices into the sheep's stomach, bakes appropriately, and is provided to a "Robert Burns night" group (with or without bagpipes and kilts) with a reading of "An Address to a Haggis":
But mark the Rustic, haggis fed,
The trembling earth resounds his tread.
Clap in his walie nieve a blade,
He'll mak it whissle;
An' legs an' arms, an' heads will sned,
Like taps o' thrissle.Ye Pow'rs wha mak mankind your care,
And dish them out their bill o' fare,
Auld Scotland wants nae skinking ware
That jaups in luggies;
But, if ye wish her gratefu' prayer,
Gie her a haggis!
A haggis? What kind of metaphor is that?
