Place it as the main reaction after the visual payoff, not under dialogue. Open the sequence with a bruh soundboard button for the deadpan beat, then let this clip carry the laugh, and finish with a baby laughing meme button if the scene needs one more escalating layer.
Über diesen Sound
This 8.4-second clip is an exaggerated laugh built around the Indonesian wkwk laugh, delivered in a squeaky, rabbit-like burst that keeps going longer than expected. It feels gleefully silly and a bit unhinged, the kind of laugh that makes a normal moment sound far more ridiculous than it actually is.
