"dougly" is a term used when one golfer borrows another golfer's brand-new driver and proceeds to hit under the ball leaving a rather visible skymark on the top of the new driver.
golfer1: so I was at the range with Ted yesterday and got to hit his new RT-7 driver!
golfer2: did you leave a dougly on it?
golfer1: haha! fortunately, no -- he would have been really pissed at me....
