Last base

You've transcended dimensions, and have fucked everything in existence, but now the fine challenge awaits you. To transcend the final base you most masturbate.

Dude:"I Have transcended human understanding and have made it to last base"
Dude:"Why are you still doing this"

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 Note it is an absolute prerequisite to attempt sex with the Fallopian tube - the 12th and penultimate base - superseded only by wound sex, such as skull fucking.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.

Military Base

A facility that consists of military-related buildings, ships, or airplanes that is strictly limited to military personal.

The tourist was so drunk he tried to enter the military base, truly perceiving himself as a member of the military.

Base 4.5

Base 4 is just sex. Base 4.5 is also sex but with a little more interest. BDSM, Role play, Face Sitting, 69, e.c.t

Man, Ashley suggested we go to base 4.5 last night. I have been waiting for this for the whole 6 months we have been dating!
