What Jennifer and Mel (the first two people two write a
definition for this word) are afflicted with. Idiocity is what causes them to be idiotic. (Actually it's a pretty useless "word", and seems to be an overcomplicated
substitute for idiocy, but
whatever.)
Mel: Here is an example of 'idiocity' in which idiocity is an
adjective - "Jake has a severe chance of inheriting his mother's idiocity."
Me: You idiot, that would make it a noun, for it to be an
adjective, it would have to read, "Jake's mother is idiocity.", which doesn't make any sense. Man you have a severe case of idiocity.
Jennifer: Hi, I can't find the 'D' key on my keyboard, so I'll just type a 'C' anywhere there is a 'D'...
Me:
I have never witnessed such idiocity.
