Integrating sociological theory on sport with Judith Butler's concept of insurrectionary speech, the author explores why and how womanliness is produced and problematized. In particular, this article investigates how participating in combat sport violates conventional womanliness by foregrounding physical capability and aggression. Using her identity as a female fighter as a starting point to engage the cultural construction of womanliness, the author connects a critical/cultural look at gender and sport with autoethnography.
