Place it at the end of a failed attempt, after a Bone Crack for the hit and before a Vine Boom to underline the defeat, then cut straight to the next try. For cartoonish wipeouts, follow it with a SpongeBob Fail instead, keeping the sequence short so the knockout stays the focus.

This 4.2-second Half-Life 2 effect pairs a sharp death cue with the limp thud and awkward flop of a collapsing body. It feels blunt and physical, turning a sudden defeat into something dramatic yet faintly ridiculous. It comes from Valve's 2004 first-person shooter, built on the Source engine, where its ragdoll physics made NPC deaths look dynamic and unintentionally funny.
