I think this term has it's roots in the idea that, if you can't fire at the flag and not be penalized, a hole is "unfair."
My club hosts a fairly elite regional fourball event each year (this year a two man team needed a combined index of 3.5 or better to get in). The course is an old Travis/Ross layout with small, severe greens.
One 140 yard par 3 has a spine running through the middle of the green, with a VERY severe slope left of middle falling off to a bunker and rough/hardpan. The right side of the green is severe also, but with no falloff from the green.
One day of qualifying, a pin was cut back/middle, slightly left of the spine. I watched play for a couple of hours and NOBODY who hit the green pin high or beyond made par (almost 3/4 putted off the green and made double or worse). On the other hand, almost everyone who played the correct shot short of the hole had a fairly easy two putt par (there were only a couple of birdies, as it still was not a putt one could be aggressive with).
What I thought was a beautifully strategic pin caused more bitching and moaning about a "tricked up" setup simply because these "elite" golfers couldn't recognize a "red light" pin.
