42nd base

While walking the side street of a largely populated city, an obese transvestite begins to engage in oral sex with his own genitals and asks you to ejaculate into his nostril. Simultaneously, your cousin sees the procedure taking place and summons her bestfriends for a group orgy along with some animals. For best orgasms, it is advised that you have a 5-some with your parents, your cousin, and her bestfriend. It is not uncommon for police officers to shoot a bullet up their anus when they see such things.
Transvestite: DUDE, watch me eat myself out while giving myself a handjob

Police officer: Can I join in and make this 42nd base?

Transvestite: No

Police officer: *shoots self in asshole*

Based God

In an interview with Complex, Lil’ B was asked what “based” meant.

“Based means being yourself. Not being scared of what people think about you. Not being afraid to do what you wanna do. Being positive. When I was younger, based was a negative term that meant like dopehead, or basehead. People used to make fun of me. They was like, ‘You’re based.’ They’d use it as a negative. And what I did was turn that negative into a positive. I started embracing it like, ‘Yeah, I’m based.’ I made it mine. I embedded it in my head. Based is positive.”

6th base

Ocular sex, including any act involving the penetration of the penis into the eye socket.

Sometimes this is referred to as an EJ. It is also sometimes referred to as "skull-fucking."
I got to 6th base with Pam last night after she took out her glass eye. I think she has brain damage now.
