Use it as the payoff at the end of a reaction edit, after the setup has made the situation look serious. Follow it with the Emotional Damage sound for a second exaggerated reaction, or open with the Bruh sound to set up the joke before the count lands.
About this sound
This 12-second Russian meme clip is built around the phrase for twenty-eight knife stabs, a blunt count that sounds deliberately over the top when used as a reaction sound. It gives a dark, deadpan jolt, funny because the wording is so stark and exaggerated, and awkward because the image it names is so grim. That clash between a plain number and a violent idea is what makes it stick.
