OMG

Commonly used acronym these days for Oh my God/goodness/gosh in text messaging and email. OMG was added to the OED in March 2011, along with LOL and FYI. Surprisingly, the OED found a written source for OMG dating from 1917 and written by none other than First Sea Lord, Admiral of the Fleet, Lord ‘Jackie’ Fisher. It is not certain, however, that Fisher coined OMG. For other abbreviations and acronyms used in text messaging and emails, there are many specialist online sources and websites.
