The process of licking a cheerio (cereal) and sticking them to the face of someone sleeping. It can also be done by crushing the cheerios into a powder, wetting the sleeping persons face, and sprinkling the powder on to it.

A crunchy, oat based cereal, shaped like tiny donuts. They come in several flavors, such as
1. regular
2. frosted
3. apple cinammon
4. honey nut
5. graham cracker

They are good for your heart, because the oat fiber is microsoluable and "scrubs" cholesteral from your circulatory system.
Hamsters and ferrets love Cheerios; they are a good training device. I love them too.

The ferret digestive system is purely carnivorous, so don't let them fill up on carb based foods, even ones that are healthy for us, like Cheerios.

Donut-shaped oat cereal that can help lower your cholesterol with a low-fat diet.

Which sounds a little silly, because even without Cheerios your cholesterol can be lowered if you just ate healthier and exercised anyway..
"Brian, there's a message in my cereal! It says 'Ooooooo'!"
"Peter, those are Cheerios."

Wrongly confused with "chesto", "cheerio!" is an expression that Togame, the self-titled Strategian from Nisio Isin's Katanagatari, uses when she hits someone. "Cheerio" later became a word to be known across the land as what the most powerful man in the country, Yasuri Shichika, yelled as he took down the Eighth Shogun of the Owari Shogunate. Thus fulfilling Togame's dying wish for the expression to be spread across the country as a shout of encouragement.
Shogun: "Please spare me! Oh, I know! I'll give you the country! Don't you want power over the country?"

Shichika: "LIKE I'D GIVE A DAMN ABOUT THAT! CHEERIO!!"

*Kills the Shogun with a strike that runs through and destroys the entire side of the building and into the ground*
