know nothing know it all 

A person who knows nothing about most topics they chime in on in conversation. This person will be 16 years old with zero experience about farming and tell a farmer about crop rotation. This person will tell a European car technician what's wrong with their car, refuse to pay diagnosis, because they used to work at Chevy in the 80s, and then bitches when the car isn't fixed.

Rather than listening and increasing their knowledge they insist to run their mouth to the point where everybody is annoyed.

Tim actually gave advice to Matt Damon about how to play Jason Bourne better? What a fucking know nothing know it all.

Mr. know it all 

Someone who believes they've got the answer to every question even if the question hasn't been asked or if they really don't have the answer (... but of course they believe they do). This is not a shy individual, but rather someone whose ego is over flowing primarily through their mouth, but seems to have come from the other end of their digestive system.

Standing in the door of his single wide, Mr. know it all gave me his latest real estate tips.

Mr. know it all told the CIA there were weapons of mass destruction in Iraq. Unfortunately, they were listening.
