When a man explains something to a woman, uninvited, about a topic she is either equally qualified or more qualified to talk on.

A male doctor explaining something to a female patient, for example, would not be mansplaining.

Examples: The guy who tried to tell Margaret Atwood about "The Handmaid's Tale", the guy who told Katie Mack, who has a PHD in Astrophysics, to "learn some science" because he thought climate change was a hoax, the man who tried to correct a woman about how to pronounce her own name correctly, an Englishman correcting a Welsh woman on her Welsh pronunciation.

See also Dunning-Kruger effect.
Look at this idiot trying to mansplain periods to women... he thinks women only have nine periods a year... wait 'til you hear his lecture on how to insert a tampon correctly!
