censor-speak

This is a new one, to me.
I was listening to my boys (11 and 7)  playing around down in the basement and they started joking/yelling at each other:
"Give me the <pause> ball!"
"No! Get your own <pause> ball! This is my <pause> ball!"
Then they would laugh.

They were censoring themselves! I was laughing and shocked!
How dare they! But it was funny. And smart that they thought of it.
I wonder if it will catch on...
