A pluto is a person who is small yet everyone cares about them because they're so important and wonderful whether or not they're apart of something.

"to demote or devalue someone or something WITH considerable cause."

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!

It's okay Pluto, I'm not a planet either.
