Hit the ceiling/roof

Pro Tip 1/3

Used to describe an extreme emotional reaction, often due to frustration or shock.

Dad hit the ceiling when he saw the dent in his new car.

Pro Tip 2/3

Not to be taken literally. Nobody is actually hitting any ceiling—it’s a metaphor for anger.

I mistakenly sent the report to the wrong client, and my boss nearly hit the roof.

Pro Tip 3/3

Used in casual conversation, not in formal writing or professional contexts.

She’s going to hit the ceiling when she hears you've lost her keys.
