A scenario, often playful and sexual, in which a person forcefully stabs a knife into a mattress and uses it as a sex toy, sometimes as part of an act or roleplay, while their partner or praises them.
The term is heavily inspired by a scene in the Book "Lights out" by Navessa Allen in which a character proposes the idea of riding a knife in a mattress.

Get the Knife in Mattress mug.Wasn't the guns because there was a mass shooter and it wasn't attention because he fled and intended not to get caught.
Hym "And getting rid of the guns only stops the people who can afford security from getting stabbed by someone with a Knife. The selfish pundit class wants themselves to be safe while they hire security for themselves and then the rest of you can just get killed in a mass stabbing or something. And he had guns. The guns did nothing to save him there. It's not the culture because he's culture is being a solipsistic incest cultists who believe the sane people are the ones who think they are immortal and that a magical reality man made the the boss of everyone by proxy. So no. The cause of the murder is whatever the cause of the murder happened to be and NOT WHATEVER SELF-INDULGENT BULLSHIT THE INFLUENCER FILTH HAS DECIDED TO MAKE UP IN RESPONSE TO THE MURDER OF ONE OF THEIR OWN. One side says it's one thing. The other side says it something else. They can't both be right. All I know this that MY thing persists. And that's all that matters."

Get the Nigger knife mug.If Jack and his hill-climbing female companion both had folding-blades tools named after them (i.e., hers would be called a "jill knife"), what sort of slicing/carving-device would be named for da clear drinkable fluid dat they were carrying their empty bucket up said incline to fill up wif some of it? Maybe a water-jet cutter?
