Chiasse is vulgar French slang, so the joke is the shocking bluntness rather than any subtle wordplay.

Because the meaning is easy to guess from the tone alone, even non French speakers reuse it for food fails, bad smells and nasty surprises.

French meme voice clip saying le pain goût chiasse, used as a gross-out reaction when food tastes terrible or something is disgustingly bad.
Six seconds of disgusted French shouting about bread that tastes like chiasse, which is crude slang for diarrhea. The delivery is over the top and revolted, like someone just took a bite and instantly regretted it. The phrase is blunt, vulgar and very visual, which is why it lands as a comedy disgust reaction. It does not sound like polite criticism, it sounds like total rejection. Creators use that extreme tone to make an ordinary bad taste, bad smell or bad idea feel hilariously catastrophic and impossible to ignore.
