The phrase "what does" by itself is incomplete and lacks context to provide a specific answer. It could be the beginning of questions like "What does the fox say?" or "What does this mean?" among many other possibilities. If the user's query is about "What does the fox say?", it is related to a popular electronic dance novelty song by the Norwegian comedy duo Ylvis, which humorously explores what sound a fox makes with various absurd sounds suggested in the song.
If the query "what does" points to something else, more context would be needed for a precise answer.
