Answer:
She used Imagery.
Imagery can be defined as the use of figurative languages to represent ideas, objects, and actions in such a way that it appeals to our physical senses.
The writer's use of this literary device will help the audience to understand that the way something looks may be described through the use of figurative languages (name calling).
The writer wants the audience to know that this name calling is indicative of their age. It is something that "children" do when they cannot think of anything else to argue but don't want to lose the linguistic war they have with each other through silence. She helps us to see that children believe that the name calling can hurt another child as much as anything else they could say or do, and it did hurts.
