Though the word may be occasionally used unfairly (for example, to describe a physically unattractive guy’s genuinely respectful attempt at striking up a conversation), “creepy” serves a vital function. No other word is as effective as describing when a man has crossed a woman’s boundary; no other word forces a man to reflect on how his behavior makes other people feel. A guy can disprove accusations of being weak by displaying strength (often in foolish ways.) But a guy can only disprove the charge of creepiness by fundamentally altering his behavior to be more genuinely respectful of women.
This, of course, is why some guys hate the word so much; it forces men to reflect carefully about how they make women feel. No wonder then that so many guys are campaigning against “creep-shaming.” After all, the sooner the term becomes socially unacceptable, the sooner men can get back to not having to think about women’s boundaries.
