Hyperbole!

I read a rhetorical article about figure of speech that came from the Encyclopedia of Britannica. It was written by the Editors of Encyclopedia Britannica. Figure of speech is an intentional deviation from a real statement that clarifies both written and spoken language. In my opinion, sometimes figure of speech is hard to explain to a person, but seems to be easy to use in writing. 

Most figures in everyday speech are made or created by extending our vocabulary that we are already familiar with. A form of speech that I personally like, is hyperbole. This is an exaggeration for an effect. An example of this would be "I am so upset i could chew nails" or "If I don't get that new purse, I will die." This is an exaggeration, and is something that really wouldn't happen but we say it for the bigger effect.  

One hyperbole that I use constantly, is the phrase “I am so tired… I am going to die.” Though that may not be a great one to use or say, I tend to use It after a long day at work and school, inferring that I am really tired and need to get some sleep now. What are some figures of speech you guys like to use?
