Place it just after the visual spit for maximum impact, then follow it with a Metal Pipe Clang to stretch the gag further, or cut to a SpongeBob Fail when the character realises the mess they made.
Über diesen Sound
This is a short metallic sound effect lasting just over a second, built around the hollow clang and wet spit of a metal spittoon being struck. It lands as a sharp, slightly gross burst that feels jarring and comic at the same time, like a punchline delivered with a tinny echo. It works best as a quick reaction noise, cutting through a quiet moment with sudden, unmistakable metal.
