Place it right after the obvious statement in your edit, then follow it with Awkward Crickets to let the awkward moment underline the point. For a bigger reaction, open with Yoooooooooooo before the reveal, so this clip lands as the payoff rather than the setup.
Sobre este som
This is a short vocal clip built around a single drawn-out fahhh, lasting just over two seconds. The stretched syllable lands as a playful, exaggerated exclamation, somewhere between a sigh and a comic groan, and it works because the sound keeps going just long enough to feel overdone. It gives a listener that knowing, amused reaction to something obvious or over the top.
