Quick Definition: The measurement of how willing a woman is to do something for you.
Compliance can be used as a way to gauge the level of attraction or comfort that a woman feels for you. Generally, the more willing that a woman is to comply with your requests, the more attracted she is to you.
In a relationship, the person who is able to get the most compliance often has the most power in a relationship. Thus, in a work setting, a manager has a lot of power because he or she is able to get others to comply with the requests. In pickup, the more alpha and dominant characteristics a man can display, the more likely he is to get compliance.
Compliance can be a good way to set precedence in an interaction, and get a woman used to the idea of doing what you say. This can be accomplished with a yes-ladder of gradually increasing requests, which slowly builds up her compliance threshold.
Women also often use compliance tests to try to shift the power dynamic in their favor.
