"Recombobulation"
Mike Johnston, at The Online Photographer:
"The signs (and the word) were the brainchild of Barry Bateman, the Director of Mitchell Airport. Harold Mester, Mitchell Airport's Public Relations Manager, said, "Whether it’s a word or not, I think we can all agree we all feel discombobulated after going through a security checkpoint and need a minute to recombobulate." According to an article in OnMilwaukee.com, not a single grammarian complained. The word was named the most creative word of the year by the American Dialect Society in 2009. It's a fun word because discombobulate is a fun word."
I love it. I've never flown through Milwaukee nor seen the sign, but it's perfect.
