A short test of your intuition: what’s the most recognized English word in the world? There are, of course, a bunch of words that everybody know in every language: please, thank you, bathroom… but this is an English word that everyone knows. Give up? The word is “OK”. I’m always sort of surprised when I see it in non-English text but most languages have made it their own.
That’s pretty amazing but the most amazing thing about the word is that it was originally a joke. Although many of us might consider the hacker love of word play a relatively modern phenomenon, it’s actually a long standing tradition, at least in English. The story of that joke is a bit long and complicated so you should follow the above link to discover all the details, including why it survived in the language while similar locutions did not.
Finally, despite what your fifth grade English teacher, Miss Frump, may have told you, the correct spelling is “OK”, not “okay” and not “ok”. That will make sense to you when you discover its origin.
I love this kind of thing but it is, after all, a well established aspect of the hacker culture. If nothing else, you can astound your parents and normie friends with this piece of arcana.
