The 'Did You Just Assume My Gender?' catchphrase became a viral sensation in 2016, primarily originating within gaming and internet subcultures on platforms like Reddit and 4chan. It was popularized as a way to satirize and parody social justice activism and the evolving discourse around gender identity. The phrase is most commonly associated with a 'triggered' reaction image, often featuring a red-haired activist known as Chanty Binx. Over time, the meme transcended its political origins to become a general-purpose reaction for any situation involving an exaggerated or unexpected response. Users frequently apply the caption to animals, inanimate objects, or fictional characters to create ironic and surreal humor that highlights the absurdity of internet outrage culture.
