Bolsonaro knife

Someone tried to assassinate Bolsonaro, but they were not successful because they used a too-short knife. So when you want to get rid of a disgusting fascist dictator, you need a Bolsonaro knife at least 10 inches long.

Don't take a chance your knife won't do the job - you need a Bolsonaro knife!

Knife Monopoly 

Knife monopoly is simple, and it makes sense since you are likely to get stabbed in the back in business anyway. You play regular monopoly, but every time you buy a house you balance a steak knife on the edge of a shelf that is suspended above you. When someone lands on that property, prior to paying you, they get the option to jump up and down on the ground to possibly shake a knife loose. They have to pay double rent for this option. If you get stabbed in the back by a knife, then you lose that property and the houses on that set of properties are cleared from the board. The knives associated with those properties are also removed from the shelf. If you put a hotel down, then you have to balance a large kitchen knife on the business shelf. If you get stabbed by that knife, you lose a single hotel. If you die from that knife, then you lose 2 hotels.

Eccentric Millionaire: I've trapped you on this island because I crave the deadliest sport...
You (nodding): Knife monopoly it is then.

Peanut Butter Knife 

The knife you used to make a peanut butter sandwhich that you set near the sink, because you’re not sure if you’re done using it. Can be used metaphorically to refer to something else.

•“Hey don’t do dishes, my peanut butter knife is by the sink. I might be hungry later.”

•“If you don’t want to be friends with her again why don’t you just deny her friend request?”
“Well, I might want to sleep with her again at some point sooo, lol. *shrug* She’s my peanut butter knife.”

“I made sure to leave on good terms with my old job in case I need them to be my peanut butter knife next summer.”
