Dumbsplaining

(mænspleɪnɪŋ)

v

1. The act of ironically revealing one's state of complete mental retardation by attempting to invoke one of a myriad of "splaining" terms such as "mansplaining" or "whitesplaining" in order to shut down an argument.

Seamus PatrickBarrett - oh sorry didn't mean to bust you out for you d--- riding using profanity. I guess wise master typo hunters don't use the naughty words. I can't never be so good at words as you.😣 again, thank you for your magnificent whitesplaining.

Justin Von Striver - I'm going to coin the term #dumbsplaining in your honor, Seamus.

Dumbspiration 

The act of putting forth a stupid, inane or otherwise impractical comment or idea that inadvertently gives rise to a much better and more valid idea. Frequently used in a contrived fashion in movies and TV shows to give the main character a means of overcoming a previously impossible problem or challenge.

In the movie Independence Day, Jeff Goldblum gets a moment of dumbspiration when his father warns him to get up off the floor before he catches a cold, thus giving him the idea of using a computer virus to stop the previously invulnerable alien invaders.
