Question

what type of figurative language is this: "Most of the time since Momma died, if someone even walks close to where I’m sleeping, I’m up in a flash"

Answer 1

Hyperbole

Step-by-step explanation:

A hyperbole is an exaggeration.

Obviously, no one can be up that fast like a "flash"; the speaker is simply using hyperbole to convey the speed with which he awakes as a result of his mother's death.

Hope this helps!
