Tom Girls is a real term. The male equivalent of tomboy. A tom girl is a boy who is feminine and likes girly stuff.
So when did "sissy" become non-pc?
Yeah. I get that. But considering this was an iPhone, and knowing how autocorrect messes stuff up, I’m inclined to believe it was a typo at this point. If you have an iPhone, type “talking to tov”. The v is right above the space bar. Autocorrect turns it into “talking to Tom”. At least it did it for me.
