Place it immediately after the funniest line in an edit, then follow it with Nelson's Ha-Ha for a second wave of reaction, or switch to Sad Violin when the joke falls flat. For a group reaction, layer Laughing Dog Meme underneath the final beat to build a shared response.
About this sound
This is an eight-second burst of loud, unrestrained laughter from a single voice, rising and falling as the person laughs harder and struggles to catch their breath. It feels contagious, silly and a little over the top, the kind of laugh that makes a joke land harder just by hearing it. Use it when a reaction needs pure, unfiltered amusement rather than a worded reply.
