It's another hot day out there in Tokyo. 43C including the heat index.
We hope everyone was safe from the typhoon that just passed through.
Today's term is "amateur hour".
We can use this when someone does something unprofessionally or when a performance is done carelessly.
Example 1
I expected the presenter to do a much better job. Was it amateur hour today or what?
Example 2
A. How was the movie?
B. The actors were terrible. It was total amateur hour.
