Devin has two words that he uses interchangeably. The words are "Mah-dee" and "Dah-me" and they can mean: Mommy, Daddy, or Mommy and Daddy.
Here is an example:
"See my pizza Mah-dee!"
"Wanna bite Dah-me?" as he so sincerely offers you a bite of his half eaten cracker.
I am not quite sure of the origin of these words, but I would guess that it has something to do with Devin trying to combine Mommy and Daddy. Out of the mouths of babes!
