A noun form of the word heinous. It is used to indicate that a person, place, or thing is so awful, so ghastly, so annoying that it becomes a sort of monstrosity in its own right. It differs from the word heinousness in that one can apply it to situations not normally deserving of the word without trivializing the word heinous.
Oh! The heinosity! I can't believe that you left a turd that hugesitting in the toilet unflushed!
Something that is both heinous, and an atrocity. May be used to describe a person, place, event, thing, state of mind, or anything else you can think of.
"Did you go to Jim's party on the weekend?"
"Ya it was a Heinocity"
"Did you hear about the serial killer that was just caught?"
"Ya, he was a heinocity"
The greatest sware in history! Used to describe something so foul and wicked that the word "heinous" is not strong enough to match. The word was first used by AVGN in his Dark Castle Review.
Bob: What did you think of the movie?
David: I hated it. It was the most heinously anus film I ever had the displeasure to lay my eyes on!
