Gobbledygook

At work today I used the word gobbledygook. A coworker commented on it being a word from a movie she saw, but she struggled to say the word back and stumbled over the consonants. I was surprised someone else was less familiar with the term. If internet dictionaries are to be believed, then the word gobbledygook was born in the middle of the 20th century.

Poking around online for a feel for how frequently (or infrequently) the word gobbledygook gets used, I learned there is a statistical formula to measure readability, created in 1969, called the simplified measure of gobbledygook.
