The 'Bro Is Flabbergasted' meme belongs to a genre of reaction images used to depict extreme shock, bewilderment, or confusion. The term itself gained massive traction on platforms like TikTok and Twitter, where users pair the word 'flabbergasted'—a somewhat formal and old-fashioned adjective—with modern, low-quality, or absurd images of people and animals looking stunned. It often features the 'Shocked Cat' or various distorted human faces. The humor stems from the juxtaposition of the sophisticated vocabulary with the chaotic energy of internet culture, making it a go-to response for situations that leave one completely speechless.
