pluto

demote or devalue a person or thing; a pluto (not capitalized) is someone or something that has lost its status (On August 24, 2006, the International Astronomical Union, which decides the official names of all celestial bodies, stated that Pluto was not a true planet because it’s “too small and doesn’t dominate its neighborhood.” They dubbed Pluto a dwarf planet. This means that there are now only eight planets in the solar system.)
