The correct response is to punch him in the face, defend your personal space with extreme prejudice.

In any case, as reported in the article, people in that situation are more likely to be paralysed by shock and doubt. A blunt, self-assured response in the moment is unlikely.
I am also suspicious of approaching HR first. Perhaps a lawyer has written about how to handle this online, especially what and how to document, how to handle any witnesses, etc., but if not I would hope my wife would talk to a lawyer first. I guarantee that HR knows how to handle the incident, but they are working on behalf of the company. That doesn't mean they are working on behalf of the manager, though, so they can be at least half-trusted (IMHO). But I would still prefer that my wife have her own source of knowledge on this situation.
