Men test ideas, while women test men. Women test men through provocation. When you test someone, you don't go easy, you go after them and poke them to see where their weak spots are.
A shit test is a manufactured greivance a woman uses to test the mettle, competence and confidence in her mate. It is an intentional provocation where she subconsciously desire for the man to put his foot down,set boundaries and demonstrate that he will not be bullied, shamed or guilted into submission.
The purpose is to confirm for her that he is capable of doing what is needed to be done to provide and protect her and her children. The subconscious thought process is; "If he can't provide and stand up to me, how will he be able to deal with other dangerous cavemen or even a sabre toothed tiger?
The worst thing you can do is to cave in to her when she is shit-testing you.
Hmm..does it ring a bell? Of course! Women, feminists are subconsciously shit-testing western men. And we are caving in like a wooden house on beach exposed to a Tsunami.
Something to ponder on.
