Noun: A person who has been eating Cheerios (or another cereal) For a long period of time, and then randomly switches to a totally different, not as good cereal. Like, from Lucky Charms to Raisin Bran. *GAG*
Hannah Montanna had been eating Cheerio's for a week straight, when she randomly switched to Cornflakes. Her brother, who has witnessed her switch of cereal, then screams CHEERIHOE!!! And walks away.
