In Bumblebee (2018), while Charlie was at her job, Bumblebee accidently vandalized her furniture in the house. Memo called Charlie, and Charlie confronts Bumblebee in the hall room:
Charlie: What were you thinking? What... I told you to hide in the garage!
(Bumblebee transform into a car)
Charlie: Great. Helpful shame spiral, Bee.
Why did Charlie say, "Helpful shame spiral" in this funny scene?
