Sarah Montgomery of Complex writes that everybody poops. But not everyone uses the same tools to carry out that biological necessity. One Reddit user recently discovered that a tool he’s been using his whole life was not, in fact, a staple in bathrooms around the world.

Cue the “poop knife,” a mechanism used by @LearnedButt’s family to break up their apparently gargantuan shits. “My family poops big,” he wrote in a post. “If anyone has laid a mega-poop, you know that sometimes it won’t flush. It lays across the hole in the bottom of the bowl and the vortex of draining water merely gives it a spin as it mocks you.” What imagery.

The user went on to explain via Reddit how his family has used an old kitchen knife for decades to slice up their fecal matter. The knife hung on a nail in their laundry room, constantly waiting for its next big task. “It was normal to walk through the hallway and have someone call out ‘hey, can you get me the poop knife?’” he explains. “I thought it was standard kit. You have your plunger, your toilet brush, and your poop knife.”

Gross.
