This paper explores nicknaming practices, focusing on their capacity to derogate and establish power differentials within a group. By examining ethnographic and psychological data, this paper contends that pejorative nicknames can contribute to unjust intra-group hierarchies and thus operate analogously to slurs within small social circles. Like expressions targeting social groups based on gender or ethnicity, pejorative nicknames can indeed elicit deep offence regardless of the speaker’s intentions or whether they occur within speech reports. Moreover, this paper advances a framework (...) suggesting i) that both forms of verbal aggression index multiple dimensional qualities such as “negative valence”, “neutral arousal,” and “high dominance” rather than discrete emotional categories such as “contempt” or “anger”, and ii) that the expression of high dominance in social interactions underlies their capacity to offend. Additionally, it translates this hypothesis into a Bayesian model of sociolinguistic variation inspired by Heather Burnett’s work on identity construction, thus integrating pragmatic reasoning into a psychologically informed framework for interpreting emotional cues.
