Methane Cuddle

While spooning (a form of cuddling), the little spoon farts into the crotch of the big spoon, warming them both.

On cold winter nights, Methane Cuddles help me sleep.

Methane Exchange

When you are eating a girls ass out and she farts in your mouth. You then hold the fart in your mouth and pass it from your mouth to hers.

"Man last night this chick and I were fucking, but she farted in my mouth when I ate her ass out"
"Did you swallow it?"
"Nah, man I just did a methane exchange and gave it back to her."
"Nice, dude"

Methuselarity

A theoretical future point in time when all of the medical conditions that cause human death will be eliminated and death would occur only by accident or homicide. A blend of Methuselah and singularity; coined in 2010 by Dr. Aubrey de Grey.

Once we reach the Methuselarity, we will live in a world where 400 year olds are getting spanked by the local 600 year old, 300 year old basement dwellers leech off their 330 year old parents, and the family 900 year old who makes the most in pensions and Social Security will outtalk everyone at the Thanksgiving dinner table and tell the entire family how things were better back when he was in his 200s.
