Is understatement used in the poem Facing It?
no, there is no understatement in the poem facing it.
When the understatement is obvious to the reader/audience, it is funny and satirical. Example: The Mike's Hard Lemonade commercial where the construction worker gets a piece of re-bar impaled through his body, and the foreman says something like, "Wow, that's gotta smart a little, huh?" Obvious understatement.
To say that the Nazis killed several thousand Jews is a huge understatement. His admission that he had some troubles as a teen was a vast understatement, as he was twice questioned concerning gang killings. An understatement is explaining something in simple or trivial terms when, in fact, the idea being explained is complex. To say it's cold outside today, is an understatement.
No. An understatement is litotes, a statement which minimizes what it is talking about. "The United States has some debt problems" is an understatement because the United States has a huge debt problem. "Robert Wadlow was a bit taller than the average" is an understatement because he was the tallest man ever. An incomplete expression is one which is not finished. "Oh, for--! Give me that!" includes an incomplete expression.
