This type of crash effect comes from the stock sound library tradition of classic American animation, where exaggerated metallic clatters were recorded to make slapstick falls sound larger than life. Similar crashes have been reused for decades in cartoons, comedy shorts and online videos because the sound is instantly recognisable even without a picture. On soundboards and in memes it is now a shorthand for disaster, often dropped into gaming clips, animations and reaction edits where a simple thud would feel too quiet.
