Place it right after the daft idea is shown, then follow it with a laugh or a buzzer to underline the mistake, and keep it as the single reaction beat in a short edit so the brain gag stays clear.

Snaptrox Cerveau is a short 2.7-second meme clip centred on the French word for brain, delivered as a quick, exaggerated reaction to a daft idea or a total mental blank. It feels playful and knowingly silly, like catching yourself thinking something completely wrong and owning it in the same breath, and it lands best as a light, teasing response rather than a serious comment.
