In recent years, the internet in South Korea has become a battleground for unprecedented gender wars. This was intensified by the emergence of Megalia, an online feminist group that was started in 2015 as a response to the misogynistic culture and discourses in male-dominated online communities. This article explores the emergence of a new form of digital feminist activism as a process through which gendered realities and feminist experiences are simultaneously augmented. We argue that female online users in Korea, by taking the online seriously as a focal site in which offline realities are not simply extended or revoked but augmented through and through, could gain a critical perspective on gender relations via the activism of fun.
