Im sorry, but the question is too vague and does not provide enough context for me to give a specific answer. The search results include a variety of different things that use the phrase "what the fuck is this," such as a YouTube video, a GitHub issue, and a book review. Without more information about what you are referring to, I cannot provide a meaningful response. Please provide more context or a specific topic for me to assist you better.
