Put this clip at the reveal point of the edit, right after the action that causes the reaction. Follow it with the Emotional Damage Sound Button for a second hit, or precede it with the Bruh Soundboard Button to set up a deadpan lead-in before the main reaction lands.
About this sound
This is a 16-second voice clip of someone shouting what the hell oh my god in an exaggerated, drawn-out way, stretching the disbelief across the whole line. It feels frantic, funny and over-the-top, like a reaction that keeps escalating instead of settling, which makes the shock sound bigger and more ridiculous with every second it continues.
