I think i can imagine this type of continual abuse. A months/years kind of thing? I've probably done something similar, but only for the day... Running jokes can even go for a week... Longer than that, and yeah, it's getting into abuse territory... The abuse isn't necessarily always one-sided either. Sometimes the grammatical standards can be a sort of abuse directed inwardly by the abusee/or? My grandma used to tell her favorite story about once every 5 years or when we would visit them... She used to be an editor for a chemical weapons school... She would exclaim with exasperation that one of her co-workers would pronounce potpourri with sounding out the "t" and a short "o"... It still bothered her even in the retelling, all those decades later... For her, it seemed to be a social rank thing... She had internalized some fleeting external event that might even be fun to say... "Paht-porry" 😆
