Relationships between girls and women have typically been explored through the lexicon of "friendship" or, where there is a presence of sexual desire, "lesbian". This article suggests the complexity and impact of female (same-sex) sociality, and its relationship to heteronormativity and power dynamics between girls and women runs deeper than the terms "friendship" or "lesbian" give rise to. Exploring social and power dynamics amongst girls and women, this article explores how gender is policed and negotiated within a framework of homosociality. Drawing on empirical research within a women's Australian Rules football team, I explore the complexity of female same-sex bonds, the negotiation of gender embodiment and performance within female homosocial spaces, and the emergence of women's own lexicons in making sense of their relationships with other women in this particular social sphere, further considering how this might be applied to other female homosocial spaces, including same-sex educational and sporting sites.
