OK

OK is one of the most common slang terms; often used to communicate approval, agreement, acceptance, or acknowledgment. The term is very fluid, with its meaning changing depending on how people use it. For example, a person may say "OK" to react to a change of plans in a text, or a person may say their food was "OK" if it was acceptable but unremarkable.

Where did OK come from?

There are many stories about where OK originated, but it started as an acronym for "oll korrect" in the late-1830s. One of the first recordings of the word was in The Boston Morning Post in an article on March 23, 1839. Soon after, other newspapers picked up OK, and it rapidly grew in popularity, persisting through the years while picking up extra meanings.

OK is now firmly established in the English vernacular. You will hear it in person, see it in texts and online messages, encounter it in social media posts, and read it in articles and emails. It has even led to other slang, including k, kk, mk, mmk, and otay.

If you are an affectionate person, you can send "OK" to send a single kiss to others. The kiss can be a comforting gesture like a mom would give to a daughter. Or, it could be a romantic kiss like a husband would give to his wife.

An example of when you might send "OK" is when saying goodbye via text to your boyfriend. Or, if you are a parent or grandparent, you can send "OK" to your child or grandchild at the end of an email message.

People rarely send OK to mean "one kiss" because most people use OK to mean "okay," which leads to confusion. Instead of sending OK, you could send BFL, GBHK, HK, K, or mwah.
