The 'When the Imposter Is Sus' meme features an edited, uncanny-valley photograph of popular Twitch streamer Jerma985, characterized by an unnervingly wide grin. The image was originally created by a fan in late 2020 as a parody of the 'Among Us' gaming craze, specifically mocking the overuse of the slang term 'sus' (suspicious). It quickly evolved from a specific streamer inside joke into a massive internet phenomenon, symbolizing surreal humor and ironic obsession. Today, it remains one of the most recognizable faces in modern meme culture, used to mock anything perceived as suspicious or unsettling.
