A poor little planet that lost its title as planet recently and is now a "dwarf" planet. Pluto is beyond the Kuiper belt and crosses paths with Neptune every something or other years. It and its moon Charon orbit around each other.
Me: Pluto lost its title as planet. I feel bad for it.
Someone else: Its not a living thing so it doesn't matter.
Me: I STILL FEEL BAD FOR IT! FOR FOURTEEN YEARS I'VE BEEN TAUT THAT THERE WERE NINE PLANETS AND NOW THEIR TELLING ME THERE'S ONLY EIGHT! WHAT THE HELL!

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.
Washington DC plutoes the country for a half billion dollars every spring with Daylight Savings Time (see news article "US lost almost half a billion dollars due to Daylight Saving Time").
