the tenacious predisposition toward being a dumb ass. an alarmingly noticeable character trait in the lives of those whose general existence tends to disprove the theory "survival of the fittest."
The CFO of our company added the number 29 and 30 and came up with a solution of 64; his general dumbassity is astounding.
When a person is being stupid you might refer to their stupidity. When a person is being an idot you might refer to their idocracy. When a person is just being a DUMB ASS you can now refer to their "dumbassity."
My boss wants me to come in early to work withoutgetting paid. I am thinking that he has a severe case of dumbassity.
