Know It All

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.

know-it-all

One given to showing off about what they know by teaching others on numerous different topics that have little relation or no relation at all to the each other or the main subject matter at hand; pedant
"I'm afraid that's not going to fix the truck, Jim. To fix a truck you have to retool it. Not that much different from fixing a television set in which you rewire the power cords. Power cords which interestingly enough came were invented in the 1800s around the same time jim crow laws were passed and The First Barbary war took place. It's interesting to note that the first law was-" "Can you tell me how to fix the truck or not, know-it-all?" snapped Jim, justifiably so.

My know-it-all father went rambling on about irrelevant shit from how to groom dogs, how to tattoo arms to how to construct a road and how to build a house instead of getting to the point about figuring out the math problem. As it turned out he didn't know how.

know-it-all wannabe

Someone who claims to have an advanced knowledge of a subject they actually know little or nothing about.
Person 1: "Hey, have you see the newest episode of House?"
Person 2: "Uh... yeah, it was awesome."
Person 1: "Have you ever even seen the show?"
Person 2: "Umm... sure... I've like... seen every episode."
Person 1: "Dude, stop being such a know-it-all wannabe."

Know-it-all

one given to teaching others all the time on all sorts of topics when their information is based personal opinion 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 stupid, whereas a know-it-all is a person who acts like an expert.

know-it-all

A person who's quick to criticize the opinions, input, or approach of others in seemingly every aspect of life, so they can correct them by presenting their own input on the topic in an instructive fashion
Amber: "I'll get Jerry some tylenol and-"

Pat: "Such nonsense. When someone feels this way, what they need is chicken noodle soup and crackers. You see, that has all the nutrition they need."

Amber: "Fine! I'll run to the store and pick up some chicken noodle soup so-"

Pat: "ACTUALLY making it from scratch is much more healthy than going to the store. You see, when it's made from scratch, you can add bits of almonds that pep up up the meal."

Amber : "Pat, quit being such a know-it-all and shove it up your ass."

know it all attention whore

Someone that will have an answer for everything, regardless if they know or not....Someone that will speak about people (to whom shes never met) in a social setting, trying to get in or fit in....Someone who will exaggerate a story told as if she's got some good gossip to spread. Someone who actually believes she's the DoGooder.....and SHE IS RIGHT AND THE WORLD IS WRONG.....They tend to be loudmouthed constantly trying to prove a point or always having to defend themselves...
