I just read an article on the origin of the phrase O.K. Interesting enough it stands for “All Correct.” In 1893 a fad in Boston and New York started that involved purposely mispelling the words in an abbreviations. For instance a phrase like “No Go” would be abbreviated as K.G. (Know Go.) O.K. is spelled out as Oll Korrect. It’s actually kind of witty playing on the irony of All Korrect being spelled incorrectly. Now you know and knowing is half the battle. GI Joe.
