What Is The Korean "4B" Movement Taking Over American Women?

After the U.S. presidential election, an unexpected phenomenon began trending on social media among women. It calls on women to reject dating, marriage, childbirth, and physical intimacy. The movement is known as 4B and is a fringe South Korean feminist movement. The name "4B" stems from four Korean words. In English, they translate literally to: no marriage, no childbirth, no dating, and no sex.
