When Diane is being thrown out of her father's house, her mother yells something.
The last word ends in "-ing!"
What does she say??
"I'd say this cloud is Cumulo Nimbus."
"Didn't he discover America?"
"Penfold, shush."

Okay... watching this now.
Diane and her Dad start to argue at the table.
Diane pushes a bowl off the table and her Mom says, "Diane, what's the matter with you? Look what you've done here."
Then, Diane starts going off at/about her Dad again.
He then says he wants her out of his house.
While he is following Diane to her bedroom, Mom is begging him, "Please, Daddy... Daddy, please...etc", to calm and let it go, most likely.
Dad reaches the bedroom door, pushes it open and begins flinging Diane's clothes at her while still yelling.
As her propels her down the hallway toward the front door, Mom says, "How much more can I take?"
That's the last thing she says in this scene.
Hope this helps.
"We're all out of cornflakes. F.U." Took me three hours to figure out F.U. was Felix Ungar!
