The state of being a constant, insufferable and predictable dumbass; when one has proven beyond all reasonable doubt that dumbassery is all he capable of whether it be in life or a particular subject.

Willful engagement in selfish, potentially dangerous behaviors; with no regard or willingness of potential consequences.
After work, I complained about my stupid boss, idiotic co-workers, and annoying customers. My boss told me this dumbassery is why he is firing me. Whatta dick!
Also:
Going to college with a giant trust fund and no parental guidance frequently leads to extensive dumbassery.
Also:
I cheated on my pregnant fiancé. She caught me when she was diagnosed with an STI that I was being treated for. Can you believe I got dumped?! She accused me of dumbassery, as I booked it out of our place!
**Updated**
I raided the capitol building and posted it on social media. Going to prison for 10-20. My family blames it on my following the president’s dumbassery.
