Place it right after the surprising reveal, then follow it with the Oh My God Meme for a bigger reaction before cutting to the next scene. For a failed plan, pair it with Emotional Damage instead, letting that second sound carry the joke while this one opens it.
Über diesen Sound
This is a very short, high-pitched voice clip of Neco Arc exclaiming 'O my gah' in a sudden, startled gasp that lasts just over a second. The delivery is silly and over-the-top, giving listeners an instant feeling of wide-eyed shock mixed with amusement, perfect for a moment that is too absurd for a normal reaction.
