Tartanry

A Guillemot chick fledging from a sea cliff in Scotland.
Before these chicks are fully grown, they shimmy to the edge
of their home cliff and jump to the open sea, where their father
 will teach them how to swim and how to grow to adulthood.

To the people of Scotland, this word is dense with meaning. 

From the Diary written by Fraser MacDonald in the November 16, 2023, issue of the London Review of Books:

Balmoral has always been a byword for biscuit-tin tartanry.

Perhaps the lexicographers at Merriam-Webster will add this word to the dictionary sooner than later, though landing upon a definition must be a somewhat delicate business.
