Will OMG go the way of OK? (A facetious phrase that became commonplace.)

I enjoy saying “oh em gee” and wonder if my grandchildren will still use this phrase just as we still use the phrase “oh kay” which in its time was also a facetious phrasing:

Etymonline:

1839, only survivor of a slang fad in Boston and New York c.1838-9 for abbreviations of common phrases with deliberate, jocular misspellings (cf. K.G. for “no go,” as if spelled “know go”); in this case, “oll korrect.”

Merriam-Webster as paraphrased in Wikipedia:

This apparently resulted from a fad for comical abbreviations that flourished in the late 1830s and 1840s. The abbreviation in this case is from the misspelled “oll korrect.”
