Know-it-all

one given to teaching others all the time on all sorts of topics when their information is based on unproven opinions presented as absolute truth; a pedagogue

"Ok, whenever you go to a party you have to wear really, really happening stuff or else no one is going to hang around you. Straw hats are what's happening. If you wear straw hats people are going to take you seriously. You also can't go wrong with sandles. Now, if you wear things like this or this you'll get beat down so it's best to just throw them out. Ok, stores! You can't go to just any place to shop. If you want to buy what you're looking for, there's only one place to go. That's over at O'Mars. Now, never, I repeat, NEVER go on the North Shore Bus. The people are going to get on your nervs on the North Shore bus and the seats are going to give you back pains. Taxis are the best way to get around in this city. If you have your hair hanging all out, all the girls are going to to be looking down their nose at you. When you want a girl to know what's going down, you have your hair in a ponytail. When you go out to eat, you want your butt to look big. You can find stuff to stick in your butt over at Omar's. It's the first thing you want to buy. Now, lesson one about boys-" "I don't have time for all this, know-it-all. I doubt all that stuff is even the case."

Some know-it-all acting like a teacher on everything instead of just shutting his mouth for two seconds.

My other attempt to describe the word know-it-all on this page was actually a description of the word "patronize" or "condescending" which is to treat someone as if they're less intelligent than you or less smarter than you are, whereas a know-it-all is a person who acts like an expert through dogmatic teaching.

Know Man

A person who claims to know everything about everything, until someone else calls their bluff and makes that person look like a fool. Basically, a know-it-all with ridiculous assumptions and little-to-no proof.

Guy 1: Did you know that this new game console was coming out, during the Summer time?

Guy 2: Stop right there, you stupid know man! I just found out from the creators, they said they plan to release said console sometime during the Fall.
