"To demote or devalue someone or something, as happened to the former planet Pluto when the General Assembly of the International Astronomical Union decided Pluto no longer met its definition of a planet."
Does not inherently note whether the demotion was with or without cause. This is the definition provided by the American Dialect Society, who coined the word.
"to demote or devalue someone or something WITH considerable cause."
- from the root word pluto, a name of a former planet, which was demoted and designated as 134340,(dwarf planet) because it didn't meet its definition of a Planet.
An employeed was plutoed from his company, for his wrongdoings.
Verb. to pluto someone or something is to downgrade, demote or remove altogether from a prestigious group or list, Like what was done to the planet of the same name.
Verb. to be hijacked by a small minority to enact special interest commandments. Thus the planet itself wasn't plutoed -- it's still the same planet it was before 2006; but the International Astronomical Union (IAU) was plutoed by less than 5% of its members to pass a controversial special-interest definition of "planet", and it's been too politically sticky to yet take the organization back from the hijackers. The US and India are also frequently plutoed, according to their citizens.
