Place this clip at the exact moment of rejection in a reaction edit, after the offending line has landed. Follow it with the Mortal Kombat Fatality sound for a mock game-over finish, or precede it with the Law & Order Dun Dun to frame the outburst like a verdict.
About this sound
An adult male voice screams 'you go to hell and you die' in a short, full-volume outburst that stretches into a theatrical curse. It feels furiously funny rather than truly threatening, because the outrage is so exaggerated and cartoonish. The clip comes from South Park, the animated series created by Trey Parker and Matt Stone.
