This isn’t done well enough by most of my friends if you ask me.
I’d like to expand on that final step, though. The key move in the delayed pocketing of the ball is to walk away toward the edge of the green inspecting the ball to make sure that shit is sparkling before it goes into your pocket. The idea here is to insinuate that you putted that thing through about a quarter mile of war-torn terrain with absolutely no concern that it wasn’t going to end up in the bottom of the cup. This works even better if your course’s greens are pristine and even better yet if the putt was for par rather than birdie.
