A person who takes an inappropriate amount of milk from the carton for his own satisfactory, leaving a very small ounce of milk inside the carton, not thinking of the others who live in the household.
By doing so, the next person who has a desire for cereal, pours the leftover milk into his cereal bowl, leaving an uneven bowl of milk and cereal.
It is basically the person, or cereal killer, leaves a small amount of milk, and someone else attempts to eat cereal, but is instead left with little milk and a lot of cereal, blaming the suspect.
