Someone just discovered that Git's developers have a bizarre obsession with bathroom fixtures. The "porcelain" commands are the clean, user-friendly ones you're supposed to touch, while the "plumbing" commands work behind the scenes where things get messy.
This StackOverflow gem has been viewed 143k times because apparently thousands of developers were silently wondering why their version control system was named after toilet parts. Imagine trying to explain to non-tech people: "Yeah, I'm having issues with Git porcelain today" and watching their concerned faces.
The real question is what other bathroom-inspired terminology we're missing. Git flush? Git unclog? The possibilities are terrifyingly endless.
