Place it at the end of a short funny sequence, after the setup and just before the final reaction shot, so it acts as the payoff. Pair it with a baby laughing meme for a second laugh, or a goofy ahh sound first to build the absurdity before this laugh closes the scene.
About this sound
This clip is a loud, exaggerated laugh with a cartoonish, over-the-top delivery that keeps bursting out as if the person cannot stop. It feels silly, infectious and playfully chaotic, turning a small joke into a much bigger moment. The sound works best as a burst of pure amusement, the kind that makes a listener grin before they even know what was funny.
