the eleventh letter of the alphabet and the most annoying letter to receive by text message. which if someone texts you only saying "k" it usually means that person has no interest whatsoever and could really care less.

Shortened version of "Okay."

Although, presently, it's used for showing the other person you are not interested in the conversation anymore.
"Yeah, I went to this awesome cafe today. I'm going to have to go again sometime."
