About this sound
This is a short Russian voice clip, about three and a half seconds long, in which a voice exasperatedly calls out Petrovich and accuses him of cheating. The blunt, profane delivery makes it feel confrontational, incredulous and funny at once, like catching a friend red-handed and saying exactly what everyone is thinking.
