More known to the younger generations, replying back to someone "K" is the texting, messaging, and internet equivalent of giving someone the middle finger, sent by someone who is displeased. Sassy, short, and not sweet

A term of acknowledgement especially without particular interest

People too lazy to spell "OK" use this letter instead.

Conversation over text or messaging

Friend: Hey, something really important came up and we'll have to reschedule our plans for tomorrow. I'm really sorry!

Friend 2: K

K 

Short for “Ok”. Used when the person using it doesn’t know there are over 1 million words in the English Dictionary, so decides to use a letter instead, because it saves 0.0549 seconds of their lives. Can you believe it? Those people who still write the full “ok” are missing out.

John: So.... just meet me at the park at 6:00.
Billy: K
John: What?
Billy: *sigh* it’s short for “Ok”. Are you happy now? Wasting those precious seconds of my life.
John: What are you taking about?
John: Billy, you there?
*your conversation has been terminated*

Modder: K.
