The exclamatory online abbreviation OMG has won the approval of the Oxford English Dictionary.
The term - short for "Oh my God" - is one of dozens of new entries in the authoritative reference book's latest online update.
Other Internet-inspired expressions given the stamp of approval include LOL, "laughing out loud"; IMHO, "in my humble opinion"; and BFF, "best friends forever".

The dictionary says that although the terms are associated with modern electronic communications, some are surprisingly old.
The first confirmed use of "OMG" was in 1917.
The new update includes "flat white" - a type of milky coffee - and "muffin top", defined as "a protuberance of flesh above the waistband of a tight pair of trousers".
