"Shit" in the context of nonsense refers to statements or ideas that lack meaning, coherence, or value. It is often used to describe conversations or arguments that are considered trivial or absurd, making it difficult to take them seriously. This term can also imply that the information presented is misleading or false. In everyday language, people might say someone is talking "shit" when they believe the person is not being truthful or is exaggerating. This usage can be found in various forms of media, including social media, comedy, and casual conversations, where humor often arises from the absurdity of the claims made.
