About this sound
A short spoken reaction clip, about four seconds long, where a voice flatly delivers the line nothing but a load of crap as a blunt dismissal. It feels fed up and cutting, turning annoyance into a quick laugh for anyone tired of excuses, bad takes, or obvious nonsense being presented as if it were true.
