I think @TheMadGardener was correct above and that they were making their own FNAF type game. I asked ChatGPT if this means anything, are they video game references, or code for something or some sort of pop culture reference and it said the below....
Interesting set of phrases! On their own, they read like oddly specific warnings or “rules,” which makes me think of a few possible contexts where lists of strange or unsettling advice show up:
Creepypasta / “Rules” horror genre → Online horror stories often take the form of “a list of strange rules you must follow” (like Rules for the Night Shift, Don’t Talk to the Man in the Hallway, etc.). Your examples — mundane advice with a slightly uncanny twist — fit that style.
ARGs (Alternate Reality Games) → Sometimes cryptic sentences like this are dropped as clues or “instructions” to players, often blending the ordinary with the unsettling.
Video game references → Not directly. I don’t see a clear link to a specific franchise. Some games (Alan Wake, Silent Hill, Five Nights at Freddy’s) use similar “rule-style” advice, but these exact lines don’t map to any known game.
Pop culture / memes → There’s a recent trend on Reddit and TikTok of creating eerie lists of “family rules” or “town rules,” which are essentially short-form creepypasta. The phrasing “the blue cup is for milk, not juice” especially feels like that kind of uncanny, very specific “rule.”
Code / metaphor → They could also just be metaphorical reminders about trust, boundaries, or tradition, dressed up in domestic imagery.
So — these aren’t standard references to a specific game or pop culture property that I can find. They line up most closely with the “weird rules horror” microgenre that circulates in online fiction.
