Hyperboles are common in everyday language and in poetry.
Read on and you will see what I mean:
We have been waiting for ages.
She wept oceans of tears.
I wouldn't do that for all the tea in China!
I was hopping mad.
I nearly died laughing.
All the perfumes of Arabia will not sweeten this little hand. (Shakespeare)
When she smiled all the world was gay.
If I had to marry him I would kill myself.
Next time you write an essay why not try putting in a hyperbole or two?
