it's a feminist movement, in backlash to misogyny and pro-natalism in South Korea (it's becoming more widespread, though).
The 4Bs are the "four no's":
no dating men
no sex with men
no marriage with men
no childbearing
It gets a lot of pushback and is called selfish etc. but women are very angry & upset that the government only sees them for their reproductive use, and it's reasonable to not want to date someone who doesn't view you as human.
