idiotsplain 

When someone who knows little or nothing about a topic attempts to explain the topic incorrectly to someone who is an expert.

Did you really just try to idiotsplain the metric system to someone with a degree in engineering?

Transcending the unnecessary that is mansplaining, idiotsplaining is when a total idiot attempts to explain something to another individual that knows the subject matter much better than they do. Examples include a man idiotsplaining how women’s reproductive organs work; an antivaxxer explaining to an epidemiologist how herd Immunity works and; an uneducated conservative explaining socialism to a political science grad.

Did you read that’s stupidity on Jane’s Facebook wall?

Oh yeah. That dude was totally idiotsplaining to her what happens during her period
