This audio is best known online as a French dismissive reaction clip rather than as a clearly documented quote from a specific film, show or creator. The phrase itself is common vulgar French slang meaning that someone does not care at all. Short uploads of it spread through meme pages, chat apps and soundboards because the attitude is instantly understandable, even for people who do not know French. Its staying power comes from how quickly it can puncture tension, mock oversharing or end a joke with pure contempt.
