   • 1914, Eleanor H. Porter, Pollyanna Grows Up, pages 38–39:

     “ […] Cities aren’t like frosted cake — and, anyhow, even the cake didn’t keep very well. I tried it, and it dried up, ’specially the frosting. I reckon the time to take frosting and good times is while they are going; so I want to see all I can now while I’m here.”

2. A layer of frost.
3. The theft of a car while it is left unattended, especially when its engine is left running in the winter to defrost the car.[1]

• The plural form is used for multiple varieties of frosting; a single type of frosting is itself uncountable.
