Put it immediately after the blunder, then follow it with Sad Violin for a slow payoff, or open with Oh My God Wow and let this clip answer it for a bigger reaction.
About this sound
This 10-second voice clip strings together a rapid run of disbelief, omg, bruh, oh hell naw, man, wtf man, delivered in one breathless escalating rant where each new phrase piles on the last. It feels stunned, exasperated and funny all at once, like catching something so wrong you cannot form a proper sentence.
