Why Not Not 

The act of a comeback to "why not" often used in a smart ass way to be funny and shut someone up from asking why.

Person 1: I'm sick.
Person 2: why?
Person 1: Why not?
Person 3: Why not not!
Person 1: .....what?

Why Not 

The only answer to the question Why.

No matter what you say, you can always ask why. The only way to end it is by saying Why Not.

Saying why after why not just doesn't make any sense!

-I like Urban Dictionary
-Why?
-Because it's a great website.
-Why?
-Well, for one it allows me to define words.
-Why?
-Cause that's the whole damn point of the site!
-Why?
-Why not?
-...

Everybody in life: "Go kill yourself"
Me: "Why Not."

Sure, why not? 

The way to end any and all conversations, discussions and arguments. The "whatever" of the new millennium.

Jane: "Do you think Obama is too thin to be the new President?"
Joe: "Sure, why not?"

Dan: "Hey, will you come and help me with some examples for this entry on Urban Dictionary?"
Leah: "Sure, why not?"

Dave: "Do you think that God, or perhaps even some higher spiritual power, does, actually exist?"
You: "Sure, why not?"

"Why Not" Bang 

When you have the option to bang someone and you have nothing better to do and can't think of a good reason not to so you go ahead.
In programming,

If not_to_bang_reason == NONE :

Return bang!

Person#1: I was there and so was he so I tossed him a "why not" bang.
Person#2: *shrug* why not!
Person#1: precisely.

Why Not You Academy 

Why Not You Academy, formerly known as Cascade Academy is a charter high school that had recently opened at the time of this post. This school has an incredibly high minority count of students. Almost no white people are existent. They are rarer than shiny Pokémon. If you a white person in Why Not You Academy it will be much harder to fit in. This school preaches on diversity and progressivism, ironically, students use homophobic and racial slurs often, you will hear the n-word said every millisecond you are there. Teachers there don't get paid enough to deal with the shitty students. Allegedly causing one of the teachers there to resign. Students there are lazy as fuck and disrespect teachers to the point where you can't help but feel sorry for them. If you are ever in a group project prepare to do most of the work, if you are lucky, you will have one shitty person to work with, but if you are unlucky, prepare to be overwhelmed and have a stroke. Actually, don't worry, if you are one of the lazy students you will be granted very generous leniency, if you have late work, they won't mark you off for it, they even make the work easier for you in some cases. Mfs can't learn for shit. But if you are an opportunist, you will thrive in this environment. Some lazy students are willing to pay to get their homework done. I guess some money can be made off of the lazy and lame. But I don't recommend to ask where they get their money from though. (Ignorance is bliss)

Why Not You Academy, the high school where racial slurs are the norm.
