This chapter introduces the stakes of the book by narrating two stories that illustrate how the dynamics of gender difference affect belonging for women who write graffiti on both an individual and a structural level. Briefly surveying the current state of Graffiti Studies, the introduction argues that without accounting for the dynamics of gender difference within graffiti subculture, graffiti grrlz (and the ways they develop strategies of resistance in order to thrive) remain invisible. The introduction then breaks into four sections: Writing Grrlz describes the interdisciplinary ethnographic method and major interventions to the fields of Graffiti Studies and Hip Hop Studies; Digital Ups introduces the importance of digital media as a mode for grrlz to connect across geographical borders, language barriers, and time zones; Hip Hop Graffiti Diaspora frames the book’s utilization of diaspora and performance to account for the multiracial, multiethnic reality of transnational graffiti subculture; and Performing Feminism “Like a Grrl” explains how and why these strategies are framed as feminist performance.
