A non-aviator asked me what’s a sucker hole. Pilots learn not to fly through a hole (sucker hole) or near a thunderstorm, because it may fill in and get nasty. It’s a meteorological temptation. Having said that, I will take a “hole” over a wall of nasty clouds anytime. Holes can get a pilot out of a predicament sometimes, but other times, they can cause a predicament.
