The line is tied to Backrooms edits, the online liminal space setting of endless yellow rooms, humming lights and exits that never appear. That setting spread from a short creepypasta post into videos, games and found footage style series, and short voice clips became an easy way to mark a scene as part of it. Clark's complaint works as shorthand for the whole mood, less about a monster appearing and more about being stuck somewhere familiar but wrong, which is why creators reuse it far beyond horror.
