When exit polls began pointing to a clear victory for Donald Trump in the US presidential election Nov. 5, Google registered a surge in search interest for the term “4B movement.” The phrase refers to an unstructured and leaderless feminist campaign that began in South Korea five years ago as a protest against the perceived oppression of women by men.

Young liberal women across TikTok and Instagram are discussing and sharing information about the South Korean feminist movement, in which straight women refuse to marry, have children, date or have sex with men.

The 4B movement, originating in South Korea, advocates for radical feminism by rejecting traditional relationships and beauty standards.
