The phrase is written in compressed internet slang, squashing c'est quoi ce truc de fdp into one unspaced title, which is how the clip circulates on soundboards. Its exact recording source is not documented, so it spreads mainly as a reusable French reaction rather than a clip tied to a known show or creator. That anonymity helps it fit almost any baffling moment. It stays popular in meme edits and chats because French insult reactions read as funnier and more dramatic, even to viewers who only catch the tone and a few words.
