Free the nipple began as a widely shared slogan and hashtag calling for equal treatment of bare chests and an end to strict censorship of women's bodies online. It spread through social media posts, protests and pop culture references, becoming a recognisable shorthand that people now recognise even without any explanation. On soundboards and in short videos, the phrase is usually used playfully rather than as a formal campaign statement, turning a serious slogan into a quick, cheeky reaction that works because almost everyone already knows what it refers to.
