When an owner of a home has a septic tank and makes you moniter your water VERY closely, limits your shower time to 2 minutes, keeps laundrey and dishes piled up hoping for the rare chance they clean themselves

Also lives pertinaciously by the phrase, "If it's brown flush it down if it's yellow keep it mellow"
Mike: Did you see Kathy's house
Joe: Oh I know it was a pigsty
Mike: I wish she would flush her toilets, clean her dishes, and do some laundry
Joe: If only she didn't have a septic tank
Mike: I know it makes her such a water nazi
