look up any word, like cunt:
 
1.
A person who tells you better, more complicated words you could have used in your previous sentence. Often a grammar nazi as well. Always annoying.
Person 1: "Dude, that was totally not needed!"

Person 2: "I think you should have said 'that was totally superfluous'."

Person 2: "Stop being such a vocabulary communist."
