Put it at the peak of a fight or fail clip, right on the hit, then follow it with the Vine Boom for a second hit or the Bone Crack to extend the gag.
About this sound
This is a roughly 1.6-second impact effect built around one heavy, sudden blow, like a fist connecting with no warning. It feels instantly satisfying and a little over-the-top, making a small on-screen hit feel bigger, funnier and more dramatic than it looks.
