People have always been discreet about the language they use when discussing where we put our poops, and history is full of examples of turd-based euphemisms. "Chamber pot" is a pretty fancy term for a poop tin, the same way that "bog" is a pretty harmless-sounding name for a poop pit. "Commode," "privy," and "night soil" all have similar etymologies.
"Aboveground manual turd removal! Hot, fresh aboveground manual turd removal!"
Every couple decades or so, a new word comes up to describe the place we leave our leavings. In some cases, like "water closet" or "toilet," we had to describe a physical device that was perhaps deserving of a new name. But even though we're now describing a device and a room that haven't changed in design or function for a century, that hasn't stopped the parade of increasingly delicate words that have been coined to describe it. Bathroom. Washroom. Restroom. Have you ever rested in a restroom? What the fuck, man? There's a line!
Are ... are you eating in there?
How long will it be before "bathroom" sounds crass to our ears and we change it to "business room" or "pudding depository"?
That's a serious suggestion, by the way. Make it happen, society.
