I think fem-terrogation is used to elicit specific info and the subject man may often not gather what is really being sought and why.

If the desired info is given, great.

If the wide-eyed probing questioning leads to bloviation on a pet subject and away from the sought data needed for mating informational purposes, then a splenetic term is applied to the subject.

Thus it is likely that ND men are often categorized thusly, as well as trying the patience of innocent questioners who are merely trying to ascertain bank balances, salary, promotion potential, and other relevant info needed to determine if she is suddenly interested in his pet subjects.

You man-splained the idea of man-splaining in a thread about a meme about the same thing. I've lost track of where the ironic joke ended.
