The problem is that in the context of AI, "slop" has lost its definition.
It originally meant low-quality content that was obviously AI that's trying to be passed off as real.
But the anti-AI crowd has co-opted the term to mean any AI-generated content, regardless of quality and the intent of its usage. Some of them refer to Expedition 33 (Which scored as one of the greatest games of 2025) as AI slop, despite AI not even being used for the final product, beyond one in-game poster that accidentally shipped with its AI placeholder rather than the hand-made asset.
