The Planetary Orbital Observation Platform - Poop?

NASA has asked Twitter users to name the probe to Uranus. One user said, probably McProbe face naturally. Someone else responds: "This seems like the perfect time for astroglyte to sponsor space exploration or the planetary orbital observation probe" Another says 'poop' because it's an acronym and people don't care about initialisms anymore. A third suggests Varuna after a Hindu deity in the names of planets.
