Inspired by GrumpyOldLady's contribution to the firefly thread. She wrote that her grandchildren called fireflies, blinky bugs. Many times children re-purpose words or phrases that become common terms within a family. Many times those words describe something in a more percise fashion, other times they are just linguistic malformations that are just plan cute.

When I was a little gnome I used the phrase "a baby bit" to denote a small serving of food. To this day, we still use that phrase.

What are some invented words in your family?
