It's a sexist-driven term because there is already a word for explaining the phenomena without attaching needless and unfounded gender implications to it i.e. condescending. You can even say "condescending and sexist" if sexism is overtly present. By coining a separate phrase all you are doing is institutionalizing a victim complex based on presumptuous and denigrative generalizations about male behavior.
It's like calling it "black chatting" when a black person talks in a theater. If that sounds wildly accusative and offensive, it's probably because it is.
