Put it near the end of a short edit, just after the setup lands, then follow it with Anime Ahh for a second reaction or Awkward Moment when the joke turns uncomfortable. Keep it as the main reaction beat and let the next clip carry the scene forward.
Über diesen Sound
This is a short, high-pitched vocal exclamation from Towa, lasting about a second, built around one stretched ueeee sound that rises and wobbles like a startled cartoon reaction. It feels playful, dramatic and deliberately over the top, the kind of noise that turns a small surprise into a joke. The delivery is bright and theatrical, making it easy to recognise even without any words around it.
