Place it directly after the complaint clip in your edit, as the response beat rather than underneath dialogue. Follow it with the Emotional Damage Meme Sound for an escalating reaction, or swap that second slot for the Bruh Sound Effect when the complaint deserves a shorter closer.
About this sound
This 12-second clip pairs a thin, squeaky violin melody with Mr Krabs delivering a flat, mocking line, the music sounding deliberately tiny and whiny. It feels sarcastically pitying and amused rather than sad, turning a complaint into a joke. It comes from SpongeBob SquarePants, where Mr Krabs performs the world's smallest violin gag.
