The sound comes from How to Sleep, a 1953 Disney short starring Goofy, in which the character's attempts to get a good night's rest turn into a series of physical mishaps. The swish, boing and landing were part of the studio's classic cartoon sound design, where exaggerated noises made silent-looking movement feel funny and readable. As old cartoons were clipped and shared online, short effects like this one were lifted for memes and video edits, and it survives because its three-beat structure fits falls, bounces and failed stunts in just over two seconds.
