when someone says something mean: k
when someone says something nice: k
when someone is annoying: k
when someone tells a dumb story: k
when someone you don't like walks in the room: k
when someone tells you to do something: k
when you get yelled at: k

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

A letter that means I hate you, fuck off.

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.

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

One of the most annoying text response you can ever get.

/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.
