Science: 1/16th second = Ann Savage Shutup! Second

Ann Savage snaps "Shutup!" at Tom Neal while riding in the Lincoln out in the desert.

If there can be the universally recognized time unit of a New York Minute, surely we can promote the Ann Savage Shutup! Second, which is actually an elapsed 1/16th of a second. That's one pretty fast Shutup!.

Also, the scorn she constantly heaps on Neal starting after she awakens in the car was real: she really did hate him. Another reason why the movie works so well.
