OMG

Newly added to the Oxford English Dictionary:

For the March 2011 release of OED Online, we have selected for publication a number of noteworthy initialisms—abbreviations consisting of the initial letters of a name or expression. Some of these—such as OMG [OMG int. (and n.) and adj.]: ‘Oh my God’ (or sometimes ‘gosh’, ‘goodness’, etc.) and LOL [LOL int. and n./2]: ‘laughing out loud’—are strongly associated with the language of electronic communications (email, texting, social networks, blogs, and so on). They join other entries of this sort: IMHO (‘in my humble opinion’) [IMHO at I n./1], TMI (‘too much information’) [TMI at T n.], and BFF (‘best friends forever’) [BFF at B n.], among others. [snip] As such usage indicates, many people would consider these recent coinages, from the last 10 or 20 years, and associate them with a younger generation conversant with all forms of digital communications. As is often the case, OED’s research has revealed some unexpected historical perspectives: our first quotation for OMG is from a personal letter from 1917; the letters LOL had a previous life, starting in 1960, denoting an elderly woman (or ‘little old lady’; see LOL n./1); and the entry for FYI [FYI phr., adj., and n.], for example, shows it originated in the language of memoranda in 1941.
