The worst thing that ever happened to the English texting language. Usually what someone replies when they don't know what else to say or they flat out dont feel like talking to you. Or when they feel like getting a punch in the face. Major text-killer Don't ever do it! Especially not to long messages.
Person 1: I miss you so much!! How are you?? We haven't seen each other in forever. I can't wait till you come to see me tomorrow. Remember to come at 5 pm.
Person 2: K
Person 1: You know what don't come!!

Person 1: I just got dumped
Person 2: K
Person 1: die..

/k/ is the weapons board of 4chan. People from around the internet post pictures and have discussions about guns, knives, swords, and other military things like camouflage and vehicles. There are also cool stories of gun users and sometimes there are gun range meetups.
I went to /k/ today and found some cool pictures of guns.

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.

Get the k. mug.
When used in a conversation, "k..." is a response to literally anything you can think of.
Tom: You're cute
Susan: k...
Tom: Today was a good day
Susan: k...
Tom: STOP ANSWERING LIKE THAT
Susan: k...

Get the k... mug.
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?

Jimmie: ... what the fuck does "k" mean?
