Place it at the peak of a successful moment, after the reveal and before the celebration continues. Follow it with a cheer to keep the energy up, or cut to a flat reaction for a comic contrast when the win turns out to be a mistake.
Über diesen Sound
This is a short Vine clip of a man shouting yes over and over in quick succession, his voice rising with each repeat across about six and a half seconds. It feels loud, gleeful and unmistakably certain, like a burst of pure agreement that is hard not to laugh at. It has since become a familiar reaction sound in fast-paced gaming and commentary videos.
