To exaggerate, overemphasize, overstate. An idiom. The 'over' is added unnecessarily and its usage is virtually always synonymous with a mere 'exaggerate', rather than a different word, as 'exaggerate' is not a neutral usage verb like the word 'do'. There is no threshold for the word 'exaggerate', so it is not possible to overdo. To 'overexaggerate' is to 'overoverstate'.
Overexaggeration differs from mesoexaggeration (commonly known simply as "exaggeration") in that mesoexaggeration strays from the truth to balance out skepticism, while overexaggeration goes beyond this to a non-believable, completely ridiculous extreme.
