When small children drop cheerios all over the floor and an adult later steps on one. Instead of exploding like a landmind, you hear a crunch and the cheerio turns to a fine powder that is almost impossible to clean up without a vacuum.
Heather: "Anna please eat your cheerios in the chair!!!"
Anna: "OK Mommy!" (Running off with cheerios in hand to see what is outside leaving a trail of cheerios.)
Tom: (Wakes from sleep, another long night of taking care of the screaming kids) "Oh I am so tired.." CRUNCH "Oh damn it, I just stepped on a cheerio landmind. Get the vacuum!!! ANNNNAAAAA!!!!!!"

When you put a cheerio in random places, around him, around school, around the town, or even on a person without that person noticing.

When you’re blowing a British guy (or perhaps multiple British men) and choke on their dick and/or cum, at which point the Man responsible for the choking can say “Cheerio” if they so choose
“Hey what happened to that girl last night? She was coughing like crazy.”
“Oh dude she was totally Choking on Cheerios in the bathroom.”
