Um dia destes vou saber o significado de Mansplaining (Inglês, 2008)

Citando:
"The term mansplaining — a portmanteau of “explain” and “man” — entered popular usage after the author and historian Rebecca Solnit published a 2008 essay titled “Men Explain Things to Me.” She described attending a party at which a man insisted on explaining to her a “very important book” he had heard about and did not immediately seem to absorb that she had written the book."
