I think the thing that irritated me the most was that after I took off my shoes and got up to be wanded, someone was already rummaging through my carry-on items without me standing by to observe - at all three airports. I suppose we are expected to automatically trust these folks simply because they have on a uniform and are federal workers, but I think most of us know better.
Amazing how new phrases just kind of infiltrate the language, but just about every flyer in the US knows exactly what that means, LOL!
