In this article, we examine dark humour in Internet posts commenting on an online Italian newspaper report published by Il Fatto Quotidiano and devoted to the 2016 terrorist attack in Nice. The analysis focuses on the linguistic forms and socio-pragmatic functions of this dark humour in the wake of the tragedy. We argue that the creative humorous posts are meant to communicate Internet users’ ideologies conceptualised as their true beliefs about the sociopolitical situation and that they are oriented primarily towards (...) criticising terrorism-related themes, notably: inept security enforcement, radical Islam, political and public reactions and integration policies. The humour in the Italian posts is used as a means of displaying Internet users’ wit and attracting other users’ attention. (shrink)
