Place it near the end of a short reaction sequence, after a Bruh sound effect sets up the failed moment and before a goofy ahh sound stretches the joke further. That order keeps the reaction building instead of peaking too soon, and it works best when each cut stays tight around the reaction.
このサウンドについて
This five-second vocal meme repeats the playful Wili Wili phrase before landing on the sharp N9ii ending, giving it a quick, bouncy rhythm. It feels silly, sudden and deliberately absurd, like a burst of nonsense that turns an ordinary mistake or strange reveal into a chaotic joke. Its phonetic hook sticks in your head after one listen.
