The last woman I had a date with had recently broken things off with a man who would bite her and her friends. Not a consensual biting kink done in private: he would bite people and they would tell him to stop but he would keep doing it. And she kept sleeping with him. He also made homicidal threats, and I'm sure other things she didn't disclose.

If the term "social skills" actually means anything, I would hope this man would be considered to have abysmal social skills. But, in telling people about this, they inevitably dissemble and tell me that social skills are "complicated" and that he could have been socially skilled elsewhere, though they're exceedingly vague on what that actually means.

It seems abundantly clear to me that "social skills" is an intentionally nebulous term ​that people say without actually meaning anything. This guy isn't the only example, but he's the most egregious. If biting and homicidal threats aren't "bad social skills", then *nothing* is and the term is meaningless. People just don't want to admit that dating is 99% about being physically attractive.
