Know it all

A walking dictionary. Somebody who either has to have 2 or more definitions per word for every one definition you type, or has to have a comeback example of the word, or another way it is used.

True Know it all- Peace is also an interjection Bart, you didn't know that because it wasn't on your list of uses of the word peace, and you were dead serious when you said it.
Bart-You're being kind of hard on me don't you think? I made a list of everything but interjection for peace, and it wasn't good enough for you know it all.

If a person is argumentative and argues with you so much it makes them a stubborn person and stubborn people like that think they are right about everything.
