Know-it-all

A name given to a person that expresses basic common knowledge about a subject, by a person that doesn't know shit about fuck on said subject.

Me: Hey Edgar, maybe you should just check to see if the outlet is blown before you start taking apart the DJ's mixing board.
Edgar: Oh dang man, that actually worked! Quit being such a know-it-all, you're making me look bad.
