The 'I'm Ethan Bradberry' meme stems from a 2016 introduction in a video by the YouTube duo MoeAndET, titled 'EXTREME KILLER CLOWN PRANK!' Ethan Bradberry introduces himself with a disproportionately high level of intensity, leaning into the camera and shouting his name. The clip quickly went viral after being featured in commentary videos by H3H3Productions, who mocked the aggressive and often scripted nature of the 'social experiment' genre. Today, the meme is used to represent an over-the-top or awkward introduction, often appearing in video remixes and image macros where a sudden, loud presence is required to disrupt the scene.
