Place it at the reveal point in a horror edit, after normal dialogue ends and before the reaction shot. Follow it with a Bruh Meme Sound Button for a comic drop, or lead in with a quieter build and save this for the payoff.

This nine-second clip is the Psycho movie sound effect, a sharp horror sting built to startle. It gives listeners an immediate tense, unsettled feeling, like danger has just appeared off screen. The effect comes from Psycho, the movie its title points to, and it works because the dread lands in a single hit.
