knuckleheadery

1. An action or pattern of actions consistant with those of a knucklehead, or a person with questionable intellegence.
2. Minor actions of innapropriate, silly, or inconsiderate behavior or behavior that causes a mild nuisance, not necessarily with such intent by the actor. It is not as severe as douchebaggery.

Shawn: Man I wish those people over there would keep it down. They are starting to bother me.
Dave: Yes, there is quite a bit of knuckleheadery going on over there.

Teacher: Hey, cut out the knuckleheadery and get your work done!

knuckleheadstrong

Simultaneously engaging in unwise behavior, or poor decision making (a "knucklehead"), while being so self-assured and confident (headstrong) in your information, data, choices, and actions that you are doomed to failure, that is, without the benefit of sheer dumb luck. Successful outcomes tend to lead to greater knuckleheadstrongness until unemployment, disaster, dismemberment, or death occurs.

That dude in charge of our diving trip was so unbearably knuckleheadstrong that he ignored the shark warnings and said he knew they weren't interested in humans. He's going to miss that leg, but on the upside he is great at swimming in circles now.

Knucklehead

A young and wild skinhead, normally a fresh-cut, probe to getting drunk and getting in fights.

That fresh-cut, Jimmy, is going to get beat-up if he keeps being a knucklehead and pissing off the older guys.
