The 'That Happened' meme is a staple of internet skepticism, primarily rooted in the popular Reddit community r/thathappened. It is used to mock social media posts that are clearly fabricated, often involving highly improbable scenarios where the narrator emerges as a hero and receives a standing ovation. Common tropes associated with the meme include the phrase 'and then everyone clapped' or 'Albert Einstein was there.' As a reaction image or text, it serves as a polite yet biting way to call out liars and attention-seekers who manufacture elaborate stories for internet clout.
