The 'Pretty Girls, Ugly Faces' meme trend originated on Reddit's r/PrettyGirlsUglyFaces subreddit in 2011, quickly spreading across social media platforms like Tumblr and Instagram. It subverts traditional beauty standards by celebrating the ability to contort one's face into intentionally grotesque or ridiculous expressions, contrasting them with a polished, attractive photo. The trend highlights the performative nature of social media and provides a relatable, self-deprecating outlet for users to show off their goofy side. It is widely used to mock 'perfect' online personas and remains a staple of body-positive, humorous internet culture.
