Place it at the opening of an edit, just before the reveal of what your friends were doing, then follow it with a shocked reaction sound for the payoff. If the reveal is embarrassing, add an awkward laugh after that reaction to close the scene.
Über diesen Sound
This is a short, roughly two-second voice clip of a man casually asking, 'What are you guys up to,' in a relaxed, slightly nosy tone. It feels light, playful and a little awkward, like catching friends mid-conversation. It is associated with Leafy.
