TSA (officially the Transportation Security Administration) is among airline folks said to stand for Thousands Standing Around.
I had a friend who worked for NASA. At one point he was involved with developing standards for airliners that fly ocean routes. The acronym was ETOPS - Extended Transport Overwater Performance Specifications. The unofficial version was Engines Turn or People Swim.
Normally, newspapers will print the full name of an organization, the first time it is mentioned in an article, then use the acronym for subsequent mentions.
A columnist named Jim Belshaw will, on occasion, write a column praising president Millard Fillmore. Several times during the column, he will mention an organization called the Society for the Preservation and Enhancement of the Reputation of Millard Fillmore, Last of the Whigs.
I think Mr. Belshaw is just trying to see if he can get a family newspaper to print the acronym in their Sunday edition.
