The 'I Know It's Pink' meme is derived from a serious educational video produced in the late 1990s titled 'Teen Sexual Harassment: It's Real, It's Wrong.' The scene features a teenage boy making a suggestive comment to a girl wearing a pink top, which is immediately followed by a graphic labeling the behavior as 'Teen Sexual Harassment.' The clip gained viral status on platforms like YouTube and TikTok due to its dated aesthetic, stiff acting, and the jarring transition between the boy's dialogue and the educational warning. It is now widely used as a reaction template to highlight awkward or unsolicited social interactions, often leaning into 'anti-meme' or absurdist humor.
