Place it at the end of a short fail or reaction edit, after the setup has finished and the joke is clear. Follow a Vine Boom Sound, then let this clip close the moment, or put a Dun Dun Dun Sound just before it to build tension before the payoff.
About this sound
This is a short, loud two-second clip built around the skull emoji reaction, with a sharp burst of sound that lands like a punchline after something outrageously funny. It feels sudden, over-the-top and deliberately dramatic, turning a deadpan moment into an instant joke. The abruptness is the point, giving listeners a quick hit of chaotic humour before it cuts out.
