Abstract The paper examines the ideological work accomplished by the use of conventionalized impoliteness formulae in third person reference, when the person being criticized or brought into disrepute is not present in the here-and-now of interaction. Drawing on Interactional Linguistics and data from audio-recorded informal face-to-face Greek conversations, the study shows that speakers mobilize conventionalized impoliteness formulae, along with other linguistic resources, in the course of third-party assessments to evaluate sociocultural experience, and establish interlocutors’ shared negative affective stance toward the third party picked on due to their national group membership. This practice reproduces everyday nationalism that unites offenders against national ‘others’. The study enhances our understanding of the recontextualization of conventionalized impoliteness formulae in talk-in-interaction, and the role of affective stance in the discursive formation of (national) identities.
