Is "you look like hell" a hyperbole?
I would classify it as a simile.
In the phrase "you look like hell", you can identify the word ' like '.
Typically, similes have the word ' like ', and if not they have ' as '. Similes compare two things using those words . In this phrase someone is comparing a person/thing to hell, and is using the word ' like '. This phrase looks more so like a simile rather than a hyperbole.
