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.

11th finger 

A sexual manouever in which a man, while fingering a woman outside of her field of vision, inserts his penis without announcing he is doing so. The act is generally employed as a means to commence intercourse with a hesitant (but willing) partner.

The term "11th finger" can also simply be slang for penis.

Chris: Well, she was kinda riding the fence about having sex with me. Since she never said no outright, I gave her the 11th finger, and that was that.

Kevin: nicely done, sir.

11th Floor Tailspin 

When two people involved in a workplace or office affair meet on the top floor of their building for a brief, but much needed, desired, and illicit midday liaison. The very top floor of many office buildings (or a portion of it) is typically not used by tenants and is reserved for the elevator machine room. It is usually only accessible by an unknown staircase, and makes a perfect hideaway for a secret office romance.

Jill: How about we take an 11th floor tailspin for lunch?

Jack: Sounds like a plan. Meet you at the stairs.

Jill: It's so dangerous! I love it!
