hairball
- n a compact mass of hair that forms in the alimentary canal (especially in the stomach of animals as a result of licking fur)
- You can add a little pat of butter on top, so that the hairball goes out the other end instead of coming up regurgitated.
- It's not often that a hairball makes headlines.
- Hairballs were flying the last week of July at the Meow Mix Gold Medal Games, where 6,000 (human) cat lovers competed in such events as the hairball toss and litter-box cleanup.
