An understanding of a concept so strong that you have a disturbing understanding of it, no no no you don't get it like I mean someone can still know about it, but not know as much as you do, usually in a depressing "oh godi get it now" sort of manner, the more of this painful knowledge is amassed the worse ones mind becomes.
