Place it right before the payoff in an edit, after a setup that shows someone stalling, then follow it with the Awkward Moment sound if they refuse, or the Eh Eh Ehhhh sound if they give in reluctantly.
À propos de ce son
This is a short, roughly one-second voice clip of someone stretching out the words 'come on' into a long, pleading 'c'moooon.' The dragged-out delivery makes it sound impatient, playful and a little desperate at the same time, like a nudge that has already been repeated too many times. It lands best as a quick, exaggerated reaction when waiting, urging or coaxing is the whole point.
