what is a poop knife

A poop knife is a knife used to chop up large pieces of feces in order to make them more flushable. It is typically a butter knife with a silicone or metal covering. The term "poop knife" gained notoriety after a Reddit user shared a story about their familys use of a rusty kitchen knife to chop up their feces. The story went viral and has since become a popular internet meme. While some people use a poop knife as a practical tool, others give it as a gag gift.
