Black students are often tasked with negotiating racial microaggressions--subtle, racialized offenses--at historically White colleges and universities. Higher education scholarship has found that when Black students speak up in response to racial microaggressions, they tend to feel overburdened with having to educate the offending party. This article demonstrates how Black students used a more empowering strategy that they called "beasting," where they utilized culturally affirming counternarratives to actively oppose racial microaggressions. In this process, Black students drew upon their own diverse knowledge base to contest and reframe dominant ideologies that stereotyped, dismissed, and devalued their racial group. These counternarratives included: (a) asserting Black intellect; (b) centering Black history, culture and perspectives; and (c) affirming the diversity within Black communities. These culturally affirming counternarratives serve as a powerful form of resistant capital for Black students. Moreover, the university context can facilitate the sharing of these narratives through Black student organizations, ethnic studies courses, and friendship networks. Black students can utilize this resistant capital in the future to navigate other historically White institutions that are critical to social mobility.
