For a long time Noah's word was "congo." I know Congo is a word but he didn't know that and he obviously didn't use it properly. He used it in place of other words. To him, it meant anything and everything. You could just throw it in anywhere.
Now the word is "pincko."
Here are some recent examples of how it is used by my kids:
referring to me, Paul, or each other, "Hey Pincko"
the response you get when you ask a question "Pincko"
Alex, when she says her prayers "in the name of pincko" (this one always gets them into trouble)
Pincko is a noun, verb, adjective, you name it.
And it is driving us crazy!!!
