Overconfidence in something.

Jack Pirogue made a bet in a bar in Cincinnati that he would make 2 of 3 darts into the double bullseye or his friends could mail his balls to the wall. He did not make the throws and had his ballsack cut off and nailed to the bar, coincidentally named Jack's. To this day if you go to the bar you can see a leathery dried up ballsack nailed to the wall.
Jack is crazy. He bet nailing his balls to the wall he could make that shot.

When you take a risk, or doing something that you normally would be not inclined to do; doing something dangerous some may see as foolish or 'crazy'; just doing 'it'
