Knifey-Spoony 

A game in which two or more players compare knives; the player with the largest knife is the winner. However, any player may choose to use a spoon instead of a knife. Any spoon beats any knife, but a player with a spoon is disqualified if another player recognizes and announces his or her use of a spoon.

"That's not a knife. THIS is a knife!"
"That's not a knife, that's a spoon."
"Ah, I see you've played Knifey-Spoony before!"

poop knife 

A knife stored near the toilet to chop giant concrete turds that would otherwise clog the toilet. Poop knives should be dull (since an accidental skin laceration would result in infection) and long-handled. Poop knives should never be used during the bowel movement.

You may want to find something else to butter your toast with, for that is my poop knife.

knifeass 

The feeling of a hot, serrated steak knife wedged up your asshole after a long, violent session of explosive diarrhea.

I have the worst knifeass today after drinking that McDonald's iced coffee.

knife poop 

Knife poop (nye-ph)(p-oo-p )- n derived from English slang - a turd that splits your butt hole because it has to stretch so far causing excruciating pain due to the interior walls of your anus being ripped i.e jagged poop.

Omg my anus is bleeding! It must have been a knife poop!
