The 'Impossibru' meme features a screen capture of a Japanese man making a face of extreme shock and disbelief during a segment of a Japanese variety show. The image first gained traction on 4chan in 2010 before spreading across the internet as a go-to reaction face for situations that defy logic or expectations. The term itself is a phonetic representation of the word 'Impossible' pronounced with a heavy accent, which quickly became a viral catchphrase. It is widely used to express incredulity, mock exaggerated reactions, or highlight a task that seems completely unachievable in a humorous way.
