Heirlingo

(n.)

A homemade family word, treasured for its originality and sentimental value in a world of obvious language and slang popularized by the social feed.

Nobody remembers which kid said it first, but 40 years later, "garnyard" remains the family heirlingo for the backyard.

Does it ring true?

From the future, or already here?

Coinage notes

Heirloom married to lingo: a word both spoken and passed down within a family, inherited like any good family story but used far more often. Sociolinguists have long studied the familect, the private dialect of a household. The heirlingo is the one word that outlives the house. The word in Rohit’s family is bullietch (pronounced BULL-EE-etch), an all-purpose exclamation for irritation, frustration or exasperation.
