It turns out we shouldn’t be surprised when grandma uses OMG in her birthday cards to you. The first known use of OMG, meaning Oh My God for those of you living under a rock, was in a letter to Sir Winston Churchill. British Navy Admiral John Arbuthnot Fisher wrote this sentence in a letter to Churchill, “I hear that a new order of Knighthood is on the tapis—O.M.G. (Oh! My God!)—Shower it on the Admiralty!”
The letter was sent to Churchill in 1917 and for those of you unaware of Victorian slang, “on the tapis” most likely means “on the table.” Our generation isn’t as clever as they thought, I guess. The acronym OMG became very popular with the debut of instant messaging, which was first introduced by AOL and later MSN Messenger became a huge hit.
Recently the Oxford English Dictionary added several words to its collection and OMG was one that was added. Now it is officially acceptable. I doubt they’ll ever add OMFG, though.
