Place it right after the reveal shot in your timeline, then follow the reaction with a fail sound meme for a bigger mistake or a bruh meme sound for a deadpan follow-up, keeping this clip first so the sequence reads clearly.

This is a 365-millisecond cartoon gulp, a single wet exaggerated swallow associated with Jerry the mouse. On its own it feels small, nervous and caught out, like the instant someone realises a mistake. It comes from the classic MGM Tom and Jerry cartoons, where such tiny reaction sounds replaced dialogue during chases and traps.
