An American woman's vision of a "nice guy" is nice to her, but mean to other people, especially other guys.

There are American women that say they want a nice guy, but are not interested in you, a nice guy. Well, here is your answer. When American women are looking for a "nice guy," they really are looking for a bodyguard guy. A guy who is nice, affectionate, and pleasant to her, but is toxic, violent, and aggressive towards other people, especially other guys, that approach within a football field of them. In other words, she is looking for the sharp spikes to point outwards, away from her and towards other people. Like being protected under the soft belly of a porcupine.
