This is a game where you try to keep what you post in a category. The rules might be a bit confusing, but here they are.
The person at the top of the page will post a word. The second person will post a word that shares something in common with the word above it. The third person will post a word that has something in common with both those words. The fourth will have to do something in common with all the words above it, and so on. Soon, there will be a category on that page that all the words fall into. All the words posted will have to be in that category until there is another page. That is when it starts all over.
Example:

:Marshmallows

: Erasers (They're squishy)

: Pom Pom

Nerf Balls!
And so on. So that's the game. I got the idea this morning and it happened to be the day that the school websense wasn't working. So enjoy!
Here's the word:
