megasm 

A combination of the words "mega" and "orgasm," to describe extreme, almost supernatural, orgasm.

The mother of all orgasms.

"She's having a megasm!"

An orgasm in which one shakes, even convulses violently, while making a very pained expression and noise.

Shin Megami Tensei NINE 

Some Japanese Xbox game.
Gained popularity from the Youtube video "NINE is Terrifying" by Marsh, and the script of the video was turned into a copypasta within the Shin Megami Tensei community.

"Shin Megami Tensei NINE is a psychological horror game about a guy who gets attacked by a giant angry scrotum at a Taylor Swift concert, and then spends several months facing horrific hallucinations from the resulting PTSD."

-Marsh, 2020

megamilf 

A monolithic milf in a league of her own, by whom all other milfs shall be measured. Attained by a female after having naturally birthed at least 3 or more children and still able to maintain a face, figure and demeanour that draws much attention from the opposite sex. Age range irrelevant; any woman capable of this feat deserves kudos over and above the standard milf.

#1:"Dude, are those her kids??"
#2:"Hell no, can't be. She's the babysitter"
#1:"Dude-- those kids just called her mommy"
#2: "Damn, she can mommy me!!"
#1:"Dude, she's wearing a red thong under 'em jeans!!"
#2:"Hell, that ain't no milf... thassa Megamilf, indeed."
#1:"Amen brother"

megasmegma

The pinnacle of cock cheese, with an odor so potent and lethal, that it could be used in chemical warfare

Johnny didn't wash his cock for two months, so when he went to work, his megasmegma permeated throughout the air and whoever breathed it in developed seizures as their skin melted off. They died soon after.
