113th base 

Few people have ever made it to 113th base, and even fewer have done all 112 of the predecessors. In order to achieve the legendary 113th base, you must find and retrieve the fabled Sword of Gamelon and kill the nearest person named Fred. After doing that, locate a woman named Susan and stab her. After that, fuck the hole that you have made.

Person 1: "Dude, I got to 113th base on Thursday."
Person 2: "The FBI are already on the way you sick fuck."

11th Base 

Having Sex in the 11th dimension.

Usually involves Supergravity and M-theory. This results in having sex with your lover of choice, then ending up with your grandmother 46 years ago, then in a different galaxy, and finally you inexplicably become a tentacle monster that, for some reason, looks like a deviation of George W. Bush.

As you drift into eternity, screaming every known and unknown language, you question why you bothered to look past 4th base. You become insane.

Then you Die.

...In other words, a fun time. =D

I went to 11th base with Jenn last night.

114th base

After receiving a prophecy from the oracle of Saint Höl, you must embark on lengthy quest to find the BFG’s left testicle. After retrieving the testicle, you must climb into the BFG’s urethra to return it to its home. After the return, you need to tickle the BFG from the inside to make him cream, pushing you out of his urethra. Afterwards you will be enlightened, spreading the gospel of the big friendly giant.

“What’s three plus four?”
“114th base”

“What”

Example 2:
“What would you do for a Klondike bar?”
“Pretty much anything, but 114th base sounds like a stretch”

11th base 

Cervical sex. Side effects include: severe pain and bleeding, 80% chance of ruining baby carrying potential, and a light feeling of death. Most likely a good idea to proceed immediately to the hospital after. Note it is an absolute prerequisite to attempt sex with the Fallopian tube - the 12th and penultimate base - superseded only by wound sex, such as skull fucking.

After 3 hours of using the osmotic cervical dilator, I penetrated directly into her womb, reaching the legendary 11th base.
