A “heck of a job” is a complete and total screw-up. It’s used, ironically, to show when one’s view of a situation is in contradiction to easily-observed facts.
The phrase comes from President George W. Bush who visited Louisiana in the aftermath of Hurricane Katrina and told FEMA chief Michael D. Brown, “Brownie, you’re doing a heck of a job.”
Brown later admitted he winced when Bush told him that: “I knew the minute he said that, the media and everybody else would see a disconnect between what he was saying and what I was witnessing on the ground. That’s the president’s style. His attitude and demeanor is always one of being a cheerleader and trying to encourage people to keep moving. It was just the wrong time and the wrong place.”
Brown resigned ten days after he was praised by Bush.
