This is the hole I throw mansplainers down. (It's a well, actually)
@embolalia Legitimate honest question (if that's possible on teh Interwebz) - can you point me to a definitive definition / guide to mansplaining, because I don't understand it. Urban Dictionary offers only biased / non-constructive / condescending... not even *definitions* really... they're just all instances of churlish counter-sniping.
@embolalia ... which don't actually lay out a reasonable explanation of the phenomena.
@cmtonkinson Wow yeah those are horrible. Mansplaining is when a man explains something to a woman which she clearly already knows, often better than the man in question. The best way to understand it is to follow prominent women, especially in STEM, and see their stories of e.g. giving a talk on a topic and then having someone come up and explain its subject matter to them.
@cmtonkinson One form of this is providing an irrelevant clarification, often in response to something which was obviously simplified to fit 140 characters or to make a joke, stereotypically starting with "Well, actually, …", thus the pun in my original post.
