"To let the cat out the bag"
My friend Lucy and I were walking down the street. We were talking about her new friend. Suddenly she let the cat out the bag by telling me that she was going to a party next week.

"Fat cat"
I called my classmate to tell him the homework. He told me that I had helped him a lot and that he invited me to go to a restaurant with him. I think he’s a fat cat!
