It means to know from the gut, to feel that we're winning the war in Iraq, that Rumsfeld had the backing of the generals, that Harriet Miers would have been a good candidate for the Supreme Court, that James Frey wrote his memoir as he remembered it. Stephen Colbert might have coined the phrase back in October 2005 in the inaugural episode of The Colbert Report, but it has reverberated through 2006. Articulating today's zeitgeist, it's been used in newspaper editorials, politicians' speeches, commencement addresses, blog posts, and shows no sign of diminishing. What's next? I vote for "justish."
