A tweet from British author Kim Goodwin with a simple chart that defines mansplaining has become a hit online, racking up over 50,000 retweets.
Now, she's published an article on the BBC website that explores mansplaining further - and even touches on male internet users who responded to her mansplaining chart with mansplaining.
"Thousands of female-appearing Twitter users started sharing the post, asking to print it on business cards or staple it to the foreheads of men," says Ms Goodwin.
"Responses from male-appearing tweeters were more mixed. Some responded with mansplaining, either explaining sexism to women or asking how women would learn if men didn't share their knowledge.
"Many said the diagram was helpful. Others wondered whether this is really a gendered behaviour; a few argued (fairly, I think) that fathers are frequently mum-splained."
Ms Goodwin goes on to cite scientific research into how communication behaviour is gendered, and also points out that men generally dislike being mansplained to themselves.
"Mansplaining may seem like a trivial issue in isolation, but how we communicate tells other people how much or little they are valued," says Ms Goodwin.
"I think it is fair to ask: if men also find mansplaining counterproductive, why, exactly, should any of us accept it as the norm?"
After suggestions of plagiarism, Ms Goodwin also tweeted a link to a 2015 mansplaining flowchart that bears striking resemblance to her own from a US woman, saying "seems the experience is pretty universal".
