It’s not the question mark, which is annoying enough in itself. It’s the growly noise that women—and some men— give to their words, usually at the end of a sentence. My theory is that it was originally an attempt to sound more masculine and therefore more authoritative, but then it got copied by those who are insecure for any reason.
It’s just a thing, a status marker. Like circle pins and Peter Pan collars were for my generation.
