K/D 

Gaming term that stands for "kill/death ratio" used to refer to the number of people you are able to kill in a game before you die. It is calculated by taking the number of people that you killed and divided by the number of deaths that you have had.

If you killed 15 people in the span of 6 lives, then your K/D would be 2.5, meaning that for every life that you have, you are able to kill about two and a half people.

"Dude, my K/D is 1.2. I suck!"

K'd 

The act of just writing k in a text/im. People generally don't like responding to such a small answer thus being k'd generally ends the conversation. If you are the one being k'd, you should assume the person that k'd you is either very mad at you, or very pissy.

1: Hey, are you ok? You seem upset.
2: I don't wanna talk about it.
1: Well I'm here if you do
2: k.
1: *thinks to them self* Wow, I can't believe he just k'd me! I'm not answering that!
