Place this clip at the very end of a reaction edit as the closing response. Follow it with a Nelson's Ha-Ha! sting if you want a second laugh, or put a Damn reaction before it to set up the disbelief first.
About this sound
An 8-second vocal reaction built from a scoffing hmph, a pointed women, and a long run of hahaha laughter that keeps going. It feels smug, teasing and a little exasperated, like someone watching a simple task turn into a full performance and finding the whole overreaction funnier than the mistake itself.
