An individual who takes a dump in a public restroom without flushing, usually in their place of employment or a place where they regularly poop. Generally, the phantom pooper abides by a set of ground rules:

1. Leave a phantom poop only if the restroom is empty so as to secure your anonymity. If another person enters the restroom while you are on the toilet, simply poop and wipe/flush as usual.

2. Throw no toilet paper in the toilet. This will allow you to show off your brown creation in its full glory, as well as leave the person who finds the phantom poop to think "Wow, no toilet paper, this must have been a ghost!"

3. Leave a phantom poop daily, ideally in the same stall at the same time. This will ensure general chaos and distrust in the workplace.
A phantom pooper began work at Jame's office, creating chaos and distrust among his co-workers. Eventually they had to install sensor flushers in the toilets to foil the phantom pooper.
