Cuach...

..means a "cup" in Gaelic, and anglicised to "quaich". One travelled with Bonnie Prince Charlie to Derby in '45. It had been around for at least 100 years before that.

It is, of course, for drinking whisky from.

Inspiring bold John Barleycorn!
What dangers thou canst make us scorn!
Wi' tippenny, we fear nae evil;
Wi' usquebae we'll face the devil!--
The swats sae ream'd in Tammie's noddle,
Fair play, he cared na deils a boddle

Robert Burns - Tam o' Shanter
