The Impossibru Guy meme features Japanese comedian Ayumu Kato and originated from a screenshot of the variety show 'Sekai Marumie! Terebi Tokuso-bu' (World's Astonishing News!). During the broadcast, Kato's face contorted into an extreme expression of shock while watching a video segment. The image became an overnight sensation on 4chan and Reddit in early 2010, typically captioned with the word 'IMPOSSIBRU'—a phonetic transcription of a Japanese accent pronouncing 'impossible.' It remains a staple reaction image for expressing total disbelief or reacting to incredible feats.
