The dried on bits of leftover cereal stuck to the edge of the bowl. If left unwashed or rinsed, these particles will immediately begin to harden into a spackle that cannot be removed by even the toughest sponge.
Alicia left her bowl of cereal on the bedside table last night, and now she is chipping away at the cereal spackle.

Get the Cereal mug.
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.
