What does "gobbledygook" mean — and why is it funny?

informal

Meaning

Language so full of jargon or nonsense that it is impossible to understand.

Where it comes from

Coined in 1944 by an American politician, Maury Maverick, who said he was thinking of a turkey 'gobbling' pompously, with a 'gook' added on the end.

Why it is funny

The humor is that the word performs its own meaning. It sounds like absolute nonsense, gobbling and clucking off the tongue — a word about gibberish that is itself a little piece of gibberish.

Used in a sentence

"The insurance contract was forty pages of pure gobbledygook."
