Sprinkling up!

The Scene: The Kitchen
Micah had just eaten breakfast, he was standing in his underwear when Ryan opened the door to the garage and a cool breeze blew in.

Micah: They're sprinkling up!!! (whining and almost crying because he's cold)
Me: What???
Micah: They're sprinkling up on my legs! They're all scratchy!
Me: Oh, you have goosebumps.
