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."

Pug Rot

When Bum Krause's teeth are covered in a thick layer of plaque, and smell like death and old Purina dog food.
The dentist told me that my teeth smell like pug rot.

digital rot

Digital Rot is the feeling of malaise and ennui which results from hours spent in a decadent, ceaseless activity, be it watching TV, listening to music, playing video games, watching porn, scrolling on social media, but is usually a combination of all of these things. This does not *have to* result from screens and digital activity, but it typically does.

While similar to mind rot, digital rot seems to be an exacerbated form, in that digital media is far more accessible, and allows a person to sequester themselves in a dungeon of their own creation for years at a time.
>A few students show up to class, John, Jack, and Jacob.

>John stares at the board aimlessly for the whole class, not writing anything, and blankly staring and glancing around the entire room.

>Jack, whispering to Jacob: "Is John okay?"

>Jacob, whispering to Jack: "He has digital rot. His girlfriend left him, so he stayed up all night doom scrolling, watching porn, and playing video games while messaging me about how sad he was."

>Jacob pokes John in the shoulder

>John has no reaction

>Jacob, whispering: "See?"

>Jack: "wow. He needs to go to church."

>Jacob: "Yeah."

Reply Rot

Refers to degenerate bots and no life morons in YouTube comment replies spamming vile edgy word vomit directed at a YouTuber's content, family, or the comment itself to make people view their channel. These bots will often have profiles relating to offensive media, and will usually have links on their channel directing to videos made by attention seeking inbred teenagers with overgrown foreheads shitting on a deceased YouTuber/YouTuber's family member.
Random Person on YouTube: This video is awesome! I'm gonna share my thoughts in the comments so other people can tell me their thoughts!
