9 ancestral tenets

Sarcastically used to refer to steroids. A reference to a fitness influencer named Liver King, who claimed to have achieved his physique 100% naturally by eating raw liver and following an ancestral lifestyle, when in reality he was taking over $10,000 of steroids per month.

CarnivoreDude37: "PUT THAT OATMEAL DOWN, YOU FUCKING PUSSIES!! YOU WEAKLINGS WILL NEVER BE AS STRONG AS ME, UNLESS YOU EAT ONLY BULL'S BALLS AND TAKE MY OFFICIAL CARNIVORE DUDE SUPPLEMENTS, NOW ONLY $199.99!!"
Bob: "Sounds like a scam! No matter how often you lift, no one can get *that* big, unless they're also following the 9 ancestral tenets."

Ancestral Species

I had to define this today in science... If you do to, it means a species that is the ancestor of another decsending species.

Wolves are an ancestral species. They created dogs with artificial selection.

Incestry

The discovery that your ancestry actually consists of a family tree that goes straight down.

Incestrophelia

The act of sex with your dead relatives. An amalgamtion of the words "Incest" and "Necrophelia"

Apparently created by a veritable linguistic genius after hearing a bit of "village gossip" in a small rural English settlement.

"Incestrophelia" Yay. Another thing to keep the locals busy.
