emo know it all 

Anyone with enough sense to completely avoid the emo trend. Those who recognize the fact that emo is a false-genre cobbled together from bits of other music subcultures and that its adherenents are fixated on clonish fashion statements and overmoted, contrived negative emotions.

Q: Why aren't you emo?
A: As an emo know it all, I understand that emo is dumb, and therefore choose to ignore the trend.

I know you are, you said you are, so what am I? 

Blatantly useless retort which younger primary school students use.

Playground Bully: Ha ha! Ernie's Crap!
Ernie: I know you are, you said you are, so what am I?
Playground Bully: I just said that you were crap, though!
Ernie: I know you are, you said you are, so what am I?

if you know what I mean 

This phrase is put at the end of a sentence to make it sound sexual.

-I like hot dogs
-My bed is broken due to the action it's been getting
-I like bananas
-someone spilled milk everywhere!
-the train is in the tunnel
-the shuttle has landed!
-let's hide in the bed

If you know what I mean!

you know I love ya 

a good opportunity to say this phrase would be after cracking a joke about someone that is somewhat insulting, but not taken to the heart.

"aww come on now, you know i love ya!"

I Know This Guy 

An "I know this guy" story is a bullshit story where one person thinks up something funny, cool, gross, weird, or sexy, but essentially untrue, and tries to pass it off as true by framing it as if it happened to someone they supposedly know. It's similar to the "I have this friend" story, where someone asks for advice about a problem that's really about them but they're too embarrassed to say so. "I know this guy" stories are purely about entertainment, however, not about seeking advice.

Jerry: "I know this guy... he caught his sister having sex with their cousin and two friends in their uncle's bed."
Joe: "Sure, Jerry. You *know* this guy. Riiight."
Jerry: "I swear! It's true!"
Joe: "Bullshit. What was the guy's name then?"
Jerry: "Well I don't *know* him, but I heard about it."
Joe: "Sure you did. Sick pervert."
