Particularly since the refugee “reception crisis” in 2015, Finland has started transforming into a more diverse and multicultural society. These societal changes have also been accompanied by sociolinguistic change, as well as language ideological debates and tensions, often manifesting in explicitly racist and xenophobic bursts of upset. In this article, our focus is on social media as a space where such societal and sociolinguistic upsets are articulated and re-worked. Drawing on recent sociolinguistic and discourse analytic work on transformative and critical popular cultural practices in social media, and studies on rap and belonging, we discuss how, in a mediatized society such as Finland, social media serve as a forum for antagonism and conflict, but also as a site for ‘talking back’. As our illustrative cases, we investigate two heteroglossic social media performances by entertainers and artists of color. In our analysis, we will show how these performances highlight and contest ideological notions of the way particular language resources are considered a key to Finnishness, as well as their role in the racialization and othering of people of color.
