Answer:
Metaphor
Step-by-step explanation:
"In that moment John was a roaring lion..."
This is a metaphor.
A metaphor is a figure of speech that pulls comparisons between two unrelated ideas or things. In this case, John is being compared to a roaring lion.
"In that moment John was a roaring lion, threatening to consume me with his pride and anger."
As for the meaning, the roaring lion metaphor suggests that John is very angry at the narrator and is lashing out (roaring) with fierce anger and pride.
