A phrase that calls for the complete extermination of males and masculinity. Usually used by angry radical feminists who cannot get a job and resort to fucking the Communist Manifesto.
This is similar to the chanting "From the river to the sea, Palestine will be free"
Person 1: "Did you know that most internet users are males?"
Person 2: "AHHAHAHAH FUCK THE PATRIARCHY!! HOW DARE YOU SAY THAT!"
