C'est honteux is a French expression that translates as it is shameful, and it is commonly used online as a short, sarcastic verdict on embarrassing behaviour. Because the phrase is instantly recognisable to French speakers and easy to understand from context, it travels well in short-form video, where creators use it to judge a clip without adding a longer explanation. Its appeal lies in that shared social judgement: one short phrase can turn an awkward moment into a joke that viewers immediately get.
