base rape

In an online game, the act of killing spawning enemies before they leave the base.

It was a total base rape that last round of Warhawk.

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!

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 Note it is an absolute prerequisite to attempt sex with the Fallopian tube - the 12th and penultimate base - superseded only by wound sex, such as skull fucking.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