Meaning: To confuse, bamboozle. To befuddle, to mess up.
As in: I don’t get quantum theory. It utterly jargogles my brain.
Origin: “Jargogle” apparently dates back to 1692, when John Locke used the term in an article for a local publication. In the article, he was sharing his ideas about getting confused by his own ideas; hence, he interjected that he might have jargogled his reader’s thoughts all the same.
“I fear, that the jumbling of those good and plausible Words in your Head. . . might a little jargogle your Thoughts. . . .”
