“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."

Get the Rotting Core in a Human Costumemug. A costume choice made popular by the swinging community in the late 90’s. The couple who arrives wearing this is meant to indicate to other swinging couples that their preference in the bedroom is anal sex. The person who wears the whiskey outfit is said to prefer to receive, where the cola wearer prefers to give. There are several variations of this costume since the 90’s, including Jack & Coke, Jack & Ginger, Whiskey & Cola.
