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 huge sitting in the toilet unflushed!

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
