overexaggerate

Etymology
From, perhaps specifically influenced by and/or.

Verb

 * 1) To exaggerate, to overstate excessively.
 * "That math test was so hard, nobody could have passed it! Albert Einstein couldn't have done it! Our professor probably had no idea how to solve those equations! I mean-"
 * "I get it, OK? Quit overexaggerating!"

Usage notes
Since already denotes excess, overexaggerate is considered redundant and therefore proscribed by some authorities.
