This article concerns itself with the ways that Black women have taken up #BlackGirlMagic as a critical reimagining of their subject positionalities as Black women. I argue that #BlackGirlMagic is a resistant imaginary that has significantly altered the contemporary western social imaginary and suggest that the intersectional ambiguity that Black women animate builds community among Black women toward collective liberation. Bringing together Kimberlé Crenshaw's concept of intersectionality, Simone de Beauvoir's concept of ambiguity, and María Lugones's concept of oppressed←→resisting subjects, I (...) argue that #BlackGirlMagic's so-called “magic” is both produced by and produces what José Medina has termed a guerrilla epistemology. In outlining the contours of this epistemology, I demonstrate how #BlackGirlMagic resists through the transmission of knowledge, the creation of a critical genealogy, its visionary orientation, and the development of an insurrectionary counterdiscourse. To illustrate, I briefly discuss how #BlackGirlMagic provides white women with an opportunity for a beneficial form of epistemic friction. In the end, I suggest that #BlackGirlMagic's ability to unite Black women transnationally bodes well for its continued effects on the western social imaginary. (shrink)
