stupidiness 

The word stupidiness is a variation of the word stupidity. It was first used on accident by a person who cannot speak English properly (obv.) Use of this term has become a way to make fun of the person who first uttered it.

The stupidiness of these people!

Stupidity-ness

The quality of being stupid, of being able to frequently or constantly display stupidity of choice, thought, word, or deed.

The stupidity-ness of College-maleducated Snowflakes is almost boundless. They are too stupid to know that the reason they can’t get a job, talk face-to-face, spell, write a grammatically correct sentence, enjoy a funny movie or why they constantly think that they are being oppressed or victimized AND HAVE RIDICULOUS COLLEGE LOANS TO PAY OF is because THEY REALLY ARE VICTIMS... not of white, heterosexual married men and fathers with jobs taking care of their families BUT INSTEAD, VICTIMS OF A college system that DIDN’T EDUCATE THEM SO THAT THEY COULD BE PRODUCTIVE AND SELF-SUFFICIENT, but instead just mass-produced them into Political Activists, armed with misrepresentations, lies and paranoid fiction and a perverse Racial Intolerance called Identity Politics. Their STUPIDITYNESS is that they SHOULD BE ANGRY AT the college faculties and curricula that took away their opportunities for an optimistic future and saddled them with the hatefulness and delusions of an ideology intent on taking away their freedoms to think, to speak, to choose for themselves, to express themselves as individuals and to improve their lot in life with hard work.

Stupiditydest 

It is the highest and the upmost form and level of stupidity a human can achieve in their lifetime and on this plane of existence as a whole. No other life form can get to this level and degree of “dumb”.

The word is often synonymous with the name “Art”. Any person with this name might be subject to this often time scary and unexplained phenomena which has been the root cause for stupidity.

Joe: yo… I am really sorry but I can feel and sense your supid.

Candice: At least I am not the stupiditydest.
