Rotting Core in a Human Costume

A person who appears normal on the outside—sometimes even charming—but beneath the surface is emotionally decayed, morally bankrupt, and entirely hollow. Often manipulative, selfish, and abusive, they wear the appearance of humanity but lack all the qualities that make someone truly human: empathy, accountability, and emotional depth.

Used to describe:

Narcissists

Emotional abusers

Pathological liars

People who destroy others while playing the victim

“He’ll smile in your face, cry on command, and then destroy your life while blaming you for bleeding. Classic rotting core in a human costume.”

“She acted like a supportive friend until the moment I crumbled—then used every secret I ever shared against me. That’s not a person. That’s a rotting core in a human costume.”

“He says all the right words about mental health and healing, but he doesn’t believe in either—he just wants control. He’s nothing but a rotting core in a human costume.”

"He volunteers at a soup kitchen, cheats on his wife, lies to his kids, and hasn’t worked in years—but still walks around like he’s the second coming. He’s not a man. He’s a rotting core in a human costume."

core i5 4200U

an intel's processor, in the core series. It is 4th generation, and usually has 8 or 4 cores. It is the worse cpu that still works. It runs windows 7, XP, and Linux Mint best. It doesnt support windows 11 and is awful at running windows 10. When i say awful, i mean it takes exactly 39 seconds to load the start menu. occasionally THE FRICKING CURSOR LAGS.

Finn: Hey John, what is your cpu?
John: it is the core i5 4200U

Demo-Core

The "genre" of a band that sounds better on their Demos rather than over produced in a hollywood studio.

Ex of bands: Linkin Park, Motionless in White, Escape the Fate, My Chemical Romance

God, Motionless in White is really demo-core now, they're new album just doesn't cut it! Same with Linkin Park!
