k. 

If someone responds back to you with k. They are giving you attitude so that means fix what you did or hop off

Person 1- hey we still hanging out today?
Person 2- sorry I can't today
Person 1- k.

When used in a conversation, "k..." is a response to literally anything you can think of.

Susan: k...
Tom: Today was a good day
Susan: k...
Tom: STOP ANSWERING LIKE THAT
Susan: k...

k 

The most annoying and infuriating way of saying "okay" or "alright". Usually accompanied by a period (k.) and often the only thing said for one person's part of a conversation. Often used by people in text conversations who are too damn lazy to type out the entire word. It's very indirect and nondescript, you can't tell how someone feels about something if they just say "k."

Don't do it. It's annoying.

Jimmie: Hey, is it cool if Johnnie comes with me tonight?
Craig: k.
Jimmie: ... what the fuck does "k" mean?

k 

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.
