Second most common (like if I'd count it) thing I hear is: "[agitated screeching] hyperboles are bad [agitated screeching]". This was also a hyperbole because I like irony.
Now, there's no real problem with characters using them when talking, because we do that too:
"I'm so hungry I could eat a horse."
"Keep fiddling with it and you'll be deader than Princess Diana."
"Well, it burns hotter than my hatred for humanity, but only a bit."
What seems to be the problem is twofold (one of them will be the topic for another day):
- Sounds idiotic (especially if drawn out long)
- Exaggerates information
How to "ensure" that the hyperbole's exaggeration of the information can be filtered by the reader?
