pedantosaur

(puh-dan-toe-sore)
-noun

The precocious and pedantic use of esoteric words in a conceited, scholarly manner. The words are dropped into a conversation so frequently that they cannot be ignored, thus giving the speaker additional undeserved attention and perpetuating the cycle.

"I couldn't understand a word he said. I stopped listening to that narcissistic pedantosaur over an hour ago."
