Plutos are the growing number of pluto (yes, the planet) sympathizers post-rejection from the IAU. These include people who grew up thinking Pluto was a planet and don't think it's fair to pick on the smallest planet in the system. Plutos mourn their loss together mostly over the internet in online forums.
