When I worked as a technical writer earlier in my career, we had a debug/prod check: If you used a series of words it would fail you in prod (refused to build). These were usually codenames of projects and such.
One afternoon, I added the phrase "[Ww]ombo\s[Cc]ombo" (it supported regular expressions) and an expansion set (&prodbomb; evaluated to &wca; &wcb; to create "womb combo") but only in prod. In debug builds, it would produce "Wombat Combat"in bright red text.
This was a useful way to mark pages as "Don't build this in prod yet" - a habit some teams had of just yolo'ing their development branches right into production instead of doing a rebase to main. More than one build was saved by it within a few months.
