A Know it all is an egotist or most likely prideful or egotistical type. Know it all is someone who acts and thinks they know everything constantly. And they like to argue with people a lot. 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. A know it all is a hardhead who thinks they are smarter than others.
Jerry is a know it all because he argues with emma because jerry thinks he knows more about science than her.
