Place it at the end of a sequence showing a pointless plan falling apart, after the fail sound and before a reaction beat. Follow it with the Bruh meme sound for a second dismissal, then cut straight to the next scene without adding another effect.
इस साउंड के बारे में
This is a two-second French movie line spoken in a calm, deadpan male voice, delivering the words 'ça ne sert à rien' as a flat dismissal. It feels dryly funny and lightly condescending, like a polite shrug that still ends the argument. It comes from OSS 117, the French spy-comedy series built around its suave, oblivious secret agent.
