Enderverse 

Enderverse is the universe derived from the fatastic book "Ender's Game" written by Orson Scott Card.

There are many books and short stories in the Enderverse. It all started with Ender's Game, and that developed into the Ender's Game series.

Ender's Game Series:
1. Ender's Game
2. Speaker for the Dead
3. Xenocide
4. Children of the Mind

Then came the spin-offs. Ender's Shadow is based on a character in Ender's Game.

Ender's Shadow Series:
1. Ender's Shadow
2. Shadow of the Hegemon
3. Shadow Puppets
4. Shadow of the Giant

Then some short stories:

First Meeting
A War of Gifts
Mazer in Prison
The Polish Boy
Teacher's Pest
Pretty Boy
Cheater
Ender's Stocking
Ender's Homecoming
A Young Man with Prospects
Ender in Flight
The Gold Bug
Investment Counselor

Then came the book "Ender in Exile" which is 1.5 of the Ender's Game Series. If someone were to read this book, they should read last, after both Ender's Game and Ender's Shadow Series for it has spoilers.

Ender's Game is the best book out of all, but Ender's Shadow Series is the better series.

There are rumors of other books to wrap them all up together.

Shadow in Flight will be the next book to come along (maybe) and then there's also a new rumor for a book called Shadows Alive. We all eagerly await these books to be released.

People who read any of these books usually find themselves caught in the Enderverse.

Person 1. "I just read Ender's Game."

Person 2. "Dude, you know what this means don't you?"

Person 1. "No."

Person 2. "It means your caught in the Enderverse!"

Uterverse 

The place where pregnant women spend most of their mental time.

"Hey, what's up with your wife? She seems distracted."

Don't mind her, ever since we got pregnant she is in her own Uterverse planning the baby's room and all that stuff.

Consuming enough alcoholic beverages to legally be considered under the influence but not so much as to comfortably act a fool and/or hit on or be hit on by undesirable members of the opposite sex

I had to call a cab last night at the bar, but I totally wasn't even buzzed!! I think I was underserved.
