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."

Do you know your enemy?
Well gotta know your enemy Wha-hur!"

Know Your Enemy

A song created and sung by the North- California band "Green Day".

Many people say the song sucks, when it really doesn't. To understand the song you have to actually listen to the lyrics.

It speaks about the second American Revolution against these greed, rich, sons of bitches.

Many lyrics that show this is a political song are

"insurgency will rise"

"gimme, gimme REVOLUTION!"

" well, you gotta know your enemy"

know point five

To see something, and have it in your brain, but not completely registered yet...hard to explain if you haven't had it happen to you. Often people who have had it happen to them try to explain it to others with the phrase "Well I knew it, but I didn't KNOW it." The word refers to the period between knowing it and...KNOWING it.

Bob: "I saw that there was no soap in the shower before I got in, but it wasn't until after I was taking a shower that I realized 'CRAP! There's no soap in here!'"
Joe: "Haha, man! You knew it point five!"
Bob: "Yeah, yeah, 'know point five...'"
