What's an example of figurative language in Chapter 10 of The Hunger Games?

Katniss uses figurative language to describe her reaction to Peeta telling Caesar and the audience that he loves her.

Figurative language is language that is not meant to be taken literally.  Figurative language can consist of similes, metaphors, personification, and other strategies. 

Here is an example of a metaphor from Chapter 10.

I press my lips together and stare at the floor, hoping this will conceal the emotions starting to boil up inside of me....

Here is an example of a metaphor from Chapter 10.

I press my lips together and stare at the floor, hoping this will conceal the emotions starting to boil up inside of me. (Ch. 10)

A metaphor is an indirect comparison.  This is a metaphor because Katniss is describing the emotions that seem to be boiling inside her, but of course nothing is literally boiling.  She is just very upset, because she has heard Peeta say that he loved her.  Katniss is not sure what is going on.  She does not know if Peeta is just playing to the cameras, of it he actually means it.

Another example of figurative language is related to this same incident.

The roar of the crowd is deafening. Peeta has absolutely wiped the rest of us off the map with his declaration of love for me. When the audience finally settles down, he chokes out a quiet “Thank you” and returns to his seat. (Ch. 10)

When Katniss says Peeta has wiped the other competitors off the map, she means it figuratively.  There is no literal map.  The map is a metaphor for competition.  The idiom of wiping someone off a map means to get rid of the competition.

What Katniss means is that Peeta instantly became the most interesting competitor with his tale of unrequited love.  Since the contestants are supposed to kill each other to win, Peeta’s comment means that he was sent to kill the one he loves.  The audience is very sympathetic to him.  Katniss is furious at him.  She does not like being used as bait for sponsors.
