What exactly is a cesspool, anyway? Basically, it's a big cylindrical hole in the ground, sometimes covered, that is used to collect liquids and solid waste that flows from a building or group of buildings.

The term is often used figuratively or metaphorically, to describe an individual or group that is mired in controversy and general ungodliness.
