Everyone I have ever met has always over-exaggerated something in their conversations. When trying to explain things to people, it is easiest to use powerful words to express the magnitude of somethings importance or significance. For example, a teenage girl might describe a Justin Bieber concert as “the best thing ever” or “the greatest moment of my life.” While it is obviously not the greatest moment of their life (although for some they may honestly believe it was), their over emphasis helps them communicate how memorable the experience was.
The problem with over-exaggeration arises because the proportionality of importance gets messed up. If I say the summer day was super hot and outside it is roasting, how do I describe the temperature of the surface of the sun? When things are over-exaggerated, they occupy a larger band on the scale of language intensity, distorting the entire range and making powerful words useless.
