Okay, maybe not entirely. But the first written use of the acronym “OMG” — meaning Oh My God, for those not hip with the kids’ lingo — came from an admiral in the Royal Navy.
In 1917, Lord John Fisher, who resigned his commission in 1915 over Churchill’s Gallipoli Campaign during the First World War, wrote to Churchill who was then Minister of Munitions about his concerns regarding the Navy’s ability to conduct a major campaign to keep the Germans from flanking the Russians via the Baltic Sea.
Also, a tapis was a kind of tablecloth, and the phrase on the tapis meant the idea was under consideration. As for Shower it on the Admiralty, I think we can all figure out what that means.
When you think about it, it makes sense an acronym would come from the military, because no one produces TLAs like the armed forces.
