A person, who leaves large dollops of "peanut butter like" shit on the inside of the toilet bowl. Usually found at the workplace, but can occur in the home. The peanut butter pooper is notoriously hard to identify, and is thought to be a supernatural/mythical being in Indian cultures of the American southwest.
The "peanut butter pooper" had struck again, leaving large clumps of crap all over the toilet bowl in the employee break-room.
