Ignoramuse - when someone is so impenetrably stupid that their ignorance is amusing. Or someone who's ignorance is so impenetrable that they are used as a muse for someone else to riff off of (think Rep. Steve King's mind boggling gall to declare Ebola airborne and that the doctors treating Ebola patients aren't to be believed).
Shockingly idiotic comments that other shockingly idiotic people glom onto as if they have even a shred of factual reality within them.
