Well, if you live in the UK, the wonderfully poly-syllabic "omnishambles" is the deserving winner. In the US, it's the much shorter and to the point "gif."
Never heard of either of them? Click here to read the article explaining what both these words mean and why they were picked. I think you can probably guess which word I prefer. Anything that is chosen for its "linguistic productivity" gets my vote.
And it's a heck of a lot better than another contender: "mommy porn" or "mummy porn", depending where you live.
