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.

Poop Knife 

An idea, tool or tradition that was originally thought to be ubiquitous, then discovered to be unique to one's own social group (usually a family), then finally revealed to be far less unique than one thought, though still rare enough that an average person will likely not know about it.

The literal poop knife (a knife used for separating large turds into smaller pieces, such that they fit down the toilet) is the best example.

I thought it was just my family that celebrated Three Kings' Day. Turned out to be a poop knife.
