An Hyperbole is an exaggerated statement about something, but of course shouldn't be taken "Seriously".
An imagery is a figurative image when you describe something as something completely different but have the same adjective.
The Cliché is an opinion with a lack of originality.
A malapropism is the mistake use of a word, maybe in orthography, grammar, etc...
In this case, we can clearly see an exaggeration "park a million miles away from the mall", because there was so much cars in the parking lot, he parked IN the parking lot but maybe in it end or so, but literally, he didn't park a million miles away. He exaggerated about parking far. So, it's an hyperbole.
Hope this Helps! :)
