Note
An abbreviation far older than the internet that made it famous. John A.F. Fisher wrote "O.M.G. (Oh! My God!)" in a 1917 letter to Winston Churchill, punning on the initials of the Order of St Michael and St George while joking about a new order of knighthood. Today it is internet slang that typically opens a reaction. Writers wary of the oath often expand the letters with a softer minced oath in place of God.
- 2Initialism of Object Management Group.
OMG published a new version of its modeling specification this year.
Several vendors sent representatives to the OMG meeting in Boston.
Note
A computing name that shares its letters with the internet exclamation, so technical writing usually spells out Object Management Group on first mention and lets context carry the rest. The "object" in the name is the programmer's sense, an instance of a class or structure, not a physical thing or a goal. Used alone it needs no article (OMG published), and it often modifies a noun, as in the OMG meeting.
