Cereal Killer 

1) Someone who kills others using breakfast cereal, or someone who goes to the store and kills cereal.

2) Someone who turns delicious Froot Loops and turns them into nasty cornflakes, or even putting juice rather than milk into another man's cereal and giving it to them.

3) Someone who eats cereal with juice instead of milk.

cereal killer 

A hired fellow-human exterminator --- often a harassassin --- who causes his marks' premature demise by forcing them to eat oatmeal or other grain-based comestible that they absolutely detest, and so said abused victim commits eventually suicide to escape said culinary coercion.

They called Ted Bundy a cereal killer, but I happen to really enjoy hot oatmeal, plain shredded wheat, and other "simple fare" breakfast foods, so Teddy's tactics would have been much less effective at getting me to bite da dust than they would have been with many other folks with more of a "sweet tooth" or "meat 'n' potatoes" meal-selection preference.
