This effect traces back to the 1944 Donald Duck cartoon Contrary Condor, where classic Disney sound design used stretched, squeaky noises to sell cartoon physics. The same strain-and-release recording later circulated as part of the Hollywood Edge library under the title Long Slow Strain stretch w-release, which helped it reach editors outside animation. Because it is so brief and instantly readable, it survived as a handy shorthand for elastic tension, and creators still reach for it whenever a pull, stretch or strained movement needs a quick comic payoff.
