This clip comes from the tradition of professional cartoon sound design, where a slide whistle, a body fall and a cymbal crash were combined to turn a simple trip into a comic event. The version here is catalogued as a Hollywood Edge library effect, a style of ready-made slapstick audio long used by animators, editors and comedy creators. Online, short library clips like this spread through soundboards and meme edits because they are instantly recognisable, need no context and fit a fall, fail or pratfall in under a second.
