This chapter describes, from a postcolonial pragmatic perspective, the illocutionary intents behind Cameroonians' code-switching from English to French and Cameroon Pidgin English (CPE) in written online interactions. Taking into account that colonialism brought into contact foreign and local languages and cultures, it is illustrated how the choice of these languages in given contexts by members of the online forums studied here is motivated by the desire to denigrate, insult, exclude and challenge -when the switch is to French -or to consolidate in-group cohesion and raise the public esteem of the in-group -when the switch is to CPE. The approach adopted here enables us to factor in (colonial) history, demography, ethnicity, and culture in the analysis of code-switching.
