The phrase works online because anxiety is a shared, everyday experience, and naming it loudly turns a private worry into something people can joke about together. Short reaction clips like this travel well in memes and video edits, where a single familiar line can set the tone for a scene without needing much context. It is especially common in content about school, work, deadlines and social pressure, where viewers recognise the feeling immediately. Its staying power comes from that recognition: the joke is not about one event, but about a feeling that keeps coming back.
