No documented original source is attached to this short clip, and its appeal comes less from a famous scene than from the feeling it names so plainly. Online, short reaction lines like this spread because they can be dropped into almost any video without needing context, and this one travels well in edits about parties, jobs, classes and trips that turn out to be a mistake. Its brevity helps too: at just over two seconds, it fits a reaction shot and leaves the visual joke to do the rest, which is why creators keep returning to it for regret.
