The phrase "what does" is commonly used as the beginning of a question to inquire about the action, meaning, or nature of something. It is often followed by a subject to ask for clarification or explanation, such as "What does the fox say?" which is also a well-known phrase from a viral song by the Norwegian comedy duo Ylvis. If the query "what does" was incomplete and more context is needed to provide a specific answer, please specify the full question or the subject to be explained. For example, "What does a fox say?" or "What does this word mean?" would guide the response more accurately. If the user was referring specifically to the popular phrase or song "What Does the Fox Say?," it is a novelty song exploring humorous and imaginative sounds a fox might make, popularized by the viral hit video from 2013 by Ylvis.
