The phrase comes from French comedian Dieudonné, whose sketch performances circulated widely online as short extractable lines. Ferme la physiquement became a meme sound because its meaning is oddly literal in French while its intent is clear in any language: stop talking, completely. Shared on soundboards and in reaction edits, the clip survives on timing rather than context, so even viewers who do not know the original sketch understand the joke from the stern delivery and use it as a comic full stop.
