The line comes from Dungeon Crawler Carl, a LitRPG story in which contestants fight their way through a deadly, monster-filled dungeon for a watching audience. In that setting, a wave that keeps coming is not a metaphor but a literal survival problem, which is why the phrase feels so vivid outside the story too. Fans have clipped short, quotable moments like this one for reaction videos, streams, and edits, where the weary delivery fits any situation that refuses to slow down. Its appeal is simple: it names overload in a few familiar words.
