Encoded chauvinism refers to subtle or indirect expressions of prejudice and superiority, particularly in language and communication, that perpetuate discriminatory attitudes without being overtly offensive. This form of chauvinism is often more difficult to identify and challenge than traditional, explicit forms.
I first met the term in Critical code studies, where it was used to describe how anti-feminist commentaries treated woman who protest in code.
