Abstract Expanding on classic theories of stancetaking and theorizing digital activism as nexus analysis, I examine how Omani Arab citizens used discourse and images to canalize a failed food boycott campaign on Twitter (X) into a united negative stance against alleged corruption. I highlight the role of multimodality, impoliteness, indirectness, intertextual references, participation framework and Arabic cultural practices in creating a multi-layered, accreted stance with manifold implicit functions (e.g., defining Omani identity, lamenting and signalling dissent). I argue for the need to widen the scope and level of analysis of stance acts to include interplays between texts, emoji, actions and images. I also highlight the role that stance can perform in expressing dissent and managing cultural face in the understudied Arabic context. I, therefore, demonstrate the multidimensionality of stance acts made visible by social media affordances and user creativity.
