The phrase "what does" by itself is incomplete but often starts questions asking for explanations or definitions of something, such as "What does the fox say?" which is a well-known viral song by the Norwegian comedy duo Ylvis from 2013. The song humorously questions the sound a fox makes, listing other animal sounds and then asking what sound a fox produces in a catchy electronic dance style. It became an international hit with over a billion views on YouTube and made a cultural impact as a novelty viral sensation.
If the intended question or phrase is different or more specific, please provide more context or keywords to clarify the inquiry.
