Place it at the cutaway itself, after your setup shot and before the reaction lands. Follow it with the Emotional Damage Meme Sound for a bigger fallout, or precede it with the Meme Button Sound Effect for a quick one-two meme sequence in edits.
About this sound
This is an eight-second Japanese voice clip built around a single playful call of 'Yajuu-chan?' delivered in a questioning tone. It feels funny and disorienting, turning a normal moment into an awkward recognition or bizarre reveal. It circulates as a Japanese meme sound in short edits and reaction posts online.
