This is a voice clip lasting just under four seconds, with someone stretching out 'oh my God' into a long, exaggerated gasp. The drawn-out delivery makes the shock feel bigger than a quick reaction, turning disbelief into something theatrical and funny. It lands best when the surprise is too much for a normal response.
