Place it at the reveal point in your edit, after a short build-up clip and before a reaction cut. Pair it with a scream meme sound for the crowd reaction, then follow with the oh my god meme sound if you want a second, smaller panic beat to close the sequence.
About this sound
A panicked voice shouts 'Oh my God, it's Godzilla' over about six seconds, stretching the name into a long rising scream. It feels terrified and wildly over the top, turning alarm into comic dread. The shout names Godzilla, the giant monster first seen in Japanese films in the 1950s.
