A woman saying “mansplaining”. Or anything else that doesn’t have much substance but is meant to belittle something logical and fact-based that was just said or done, or the (often male) person who said or did it. The (stereo)typical female reaction to what she, while chickdissing, will call “mansplaining”. In other words, what a woman might do after she grew impatient with a man’s talking about something he happens to know stuff about. Or after she grew impatient for no reason obvious to the man talking to her, or to anyone else.

Literally everyone, ever. Including the writer of this definition.
