The term combines two similar-sounding words, "herky" and "jerky", which individually communicate a sudden, irregular, and jerky movement. "Herky" likely derives from the word "hurky", which was used in the early 1900s as a slang term meaning "awkward" or "jerky". It is believed to have originated from the word "hurk", which means to heave or jerk suddenly.
On the other hand, "jerky" has a similar meaning - describing a sudden, uneven, or jolting movement. It likely comes from the word "jerk", which has been used since the 16th century to mean a sudden, sharp pull or movement.
