Place it at the end of a fail or roast edit, just after the mistake is clear, as the final reaction. For a bigger build-up, open with the Wrong Answer Game Show sting, then let this clip close it, or swap in the Laughing Dog Meme for a second reaction and finish with Nelson Ha Ha.
About this sound
This is a short, roughly three-second clip of a cat giving a high, chattering laugh that sounds more like a teasing giggle than a normal meow. It feels smug and mischievous, like the cat is enjoying someone else's slip-up. That mocking tone makes it an instant cue for a roast, turning a small mistake into something funnier.
