Place it just before the reveal in an edit, then follow the discovery with Run Vine as the character flees and Scream Meme as the panic peaks, keeping the lurking moment as the setup for the chase that follows.
About this sound
This five-second clip plays on the idea of Shia LaBeouf lurking nearby, turning a quiet, watchful presence into a short meme sound. It feels tense and funny at once, like being spotted by someone who was already standing there, and it lands as a sudden, knowing reaction rather than a drawn-out joke.
