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.
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.
