New additions to the Oxford dictionary: "LOL" and "OMG" and a few others.
Just a small quote for younger people who believe this abbreviations were invented recently:
"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"
