What it means: Context Rot
Context rot is the name you give a chat that felt helpful an hour ago and now needs everything explained again. The assistant remembers the abandoned plan, forgets the one detail you care about, and confidently combines three different versions of your request. In casual use, the phrase captures that familiar irritation. It is not a diagnosis of every mistake in a long conversation, or proof that the model has literally forgotten something.
How people use it
We started planning a holiday and somehow it is still following the dinner instructions from forty messages ago. Context rot.
It often comes with a tiny ritual: abandoning the old chat, opening a fresh one, and introducing yourself to the same assistant all over again. The phrase lets people compare that experience without needing to agree on exactly what caused it.

Why it matters
The cultural interest is in the human response: we develop patience, frustration and little coping routines around a conversational tool. Starting a new chat can feel like getting a fresh start with someone who has stopped listening, even though there is no person on the other side. The language makes that awkward experience easier to share.
