Food consumption is used as a symbol for social status in the play. The more food is consumed by a person, the higher is his social status and the more prominent people he knows. Oscar Wilde uses the play to show that excessive society.
Sentences? How about this:
Hitting the tree put a dent in my car.
I found a stash of candy hidden under my brother's pillowcase.
Or if you need them both in one sentence:
I tried to get to the stash of food behind the metal door, but I could barely make a dent.
Is that what you needed?
