"Male privilege is “I have a boyfriend” being the only thing that can actually stop someone from hitting on you because they respect another man more than they respect your rejection/lack of interest."
The Sociological Cinema
There was actually research that was done that found that women who used an “I have a boyfriend/husband” excuse to reject unwanted sexual attention and harassment by their bosses were more likely to be left alone than those who used any other excuse (including “I’m not interested”)
When rejecting men, I’ve learned to tell them that I have a boyfriend rather than the truth, which is that I have a girlfriend. When I tell them that I have a boyfriend, they back off, but when they know that I have a girlfriend, they tend to keep pursuing me anyway.
