Yay High

Yay High (or Yay Big) simply just means you don't know about the height of a noun. (Ex: a person or an object.) In explaining the person or object's height, you tend to use your arms to show length and/or height.

How tall is John Doe?
He's about, yay high. *using his arms to demonstrate*
