What is a grey man?

The term "grey man" is often used in popular culture and military and survivalist circles to refer to a person who is unremarkable, average-looking, and easily blends in with a crowd. The idea is that by being a "grey man," one can avoid drawing attention to themselves and stay safe in potentially dangerous situations.

In the context of survivalism, being a grey man is seen as a way to stay low-key and not stand out in a disaster or emergency situation. This can involve dressing in plain, neutral-colored clothing, avoiding flashy or attention-grabbing behavior, and generally trying to blend in with the environment.

In military and espionage circles, being a grey man can involve being able to operate covertly and gather information without attracting suspicion. This may involve being able to adapt to different social situations, blend in with different cultures, and gather intelligence discreetly.

Overall, being a grey man is about being able to navigate situations without drawing unwanted attention to oneself, whether in everyday life or in more extreme circumstances.
