Who knew that the acronym “OMG” was almost 100 years old? Shown above is the earliest known usage of the abbreviation, found in a correspondance from 1917 sent by a British Admiral named John Arbuthnot Fisher to none other than former British PM Winston Churchill. The sentence in question located right below reads:
“I hear that a new order of Knighthood is on the tapis — O.M.G. (Oh! My God!) — Shower it on the Admiralty!!” [sic]
Of course, the simple abbreviation has taken on an entirely new life of its own since the time the letter was written. It was eventually added to the Oxford English Dictionary in 2011, making it only one in a line of abbreviations that have become prevalent in everyday speech.
