Ok as 0 killed
Even wondered about the origin of the word “ok”? Some people say that the word “okay” is an acronym of “Oll Korrect“; however, a probable approach is that, during the American Civil War, there was a custom to write in the daily report the number of deads; if none, they wrote 0 killed, or simply “ok”
