A portmanteau of 'poo' and 'water', referring to a mixture of the two substances. Pwater can be made up of any ratio of poo and water, from small traces of fecal matter to the substantially more pooey contents of a diarrhea-filled toilet bowl.

Pwater is a source of many illnesses, including pinkeye and Typhoid.
1. "I can't believe you let your dog drink from the toilet bowl. It may have been flushed, but the liquid in there is still pwater"

2. "International development organizations should spend less money on administrative costs and put more effort into reducing the prevalence of pwater in the developing world, where it is responsible for many diseases and deaths."
