(third-person singular simple present overexaggerates, present participle overexaggerating, simple past and past participle overexaggerated)
- To exaggerate, to overstate excessively.
- "That math test was so hard, nobody could have passed it! I mean, 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!"
As exaggerate already denotes excess, overexaggerate is considered redundant and therefore proscribed by some authorities.
over- + exaggerate, perhaps influenced by terms like overstate
