The exact recording behind this 'tas de merde' clip is not documented, which is common for short reaction sounds traded on meme soundboards. The phrase itself is everyday French slang for expressing contempt toward something worthless or botched. Online, French-speaking creators use it the way English speakers use a blunt exclamation, dropping it over gaming fails, bad takes and cringe compilations. Its appeal as a disgusted reaction is that it sounds harsh to non-speakers while remaining playful to those who understand it.
