Place it as the punchline after a long, self-important setup, then follow it with Bruh for a second reaction and Emotional Damage when the other person pretends to be hurt. Keep it as the final word in the exchange so the dismissal closes the scene.
About this sound
This four-second voice clip is a loud, exasperated shout of OMG, who the hell cares? delivered with sharp, fed-up energy. It feels blunt, impatient and funny, like cutting off a story that has gone on far too long. The line comes from SMG4, the Mario-inspired web series, where its over-the-top delivery turns a simple dismissal into a punchline.
