Jack Moment

A Jack moment is when you have an incredibly easy putt/hit, but because you are getting over par your pride persuades you to full force your ball into the nearest out of bounds zone in dramatic display of childish incompetence.

Person A: All my boys out here are cracked at golf.
Person B: Nah dude, Kyle is having a Jack moment cause he went over par.
