Place this clip at the exact moment of impact in a fail edit, after a punch sound effect for the hit itself, then follow it with a bone crack sound effect if the fall needs a second beat before you cut away.

This clip is a very short distorted vocal grunt, a stretched 'uuhhh' oof pushed loud until it clips and buzzes. At under a second it lands as pure overreaction, turning a tiny stumble, miss or loss into something that feels absurdly painful, silly and instantly funny to hear.
