Place this clip at the exact frame of the betrayal, then follow it with a damn meme sound button for the stunned aftermath. For a build up, put a sudden suspense sound button just before it, so the callout lands as the payoff in your edit sequence.
About this sound
This is a short three-second voice clip of a man angrily shouting the insult you son of a bitch at someone off screen. The delivery is loud, sharp and confrontational, which makes it feel furious and accusatory in the moment. Used as a reaction, that raw anger turns comic, giving listeners an exaggerated sense of betrayal and outrage.
