Clips built around stretched out laughing sounds like this became a staple of meme soundboards because they say more than a normal laugh track ever could. Instead of signalling a polite chuckle, this kind of cackling wail gets used to mark something as deranged, evil in a funny way, or so stupid it broke the person laughing. It circulates in short edits, reaction videos and gaming highlights where creators need an instant audio cue for chaos without adding any dialogue or explanation on screen.
