The title Hu Lue is the romanised form of the Chinese word 忽略, which means to ignore, neglect or overlook something. No specific film, show or creator is confirmed for this very short clip, so it is best understood as a user-shared reaction sound rather than a quoted line from a known work. Online, short single-word clips like this travel easily because they need no translation of tone to be understood in context. Creators use it as shorthand for deliberate indifference, especially in fast meme edits where a single word can end a joke.
