chat kill 

By definition a "chat kill" is when you stop the chat. Technicalities include:

1 - You have to be the one who posted last.
2 - It must be at least 10 minutes before you "claim the chat kill"
3 - No one can say anything during those 10 minutes for the chat kill to count.

Chat-Killer 

A post in a chatroom, forum, or other means of instant messaging which causes all of those participating in the discussion to quit replying, or cause a significant delay in posts back, comparable to an awkward silence.

"The phrase, 'Hail Satan' is a real chat-killer on most Christian servers."

chatkill 

This phenomenon often takes place in IRC. Some people are very adept at causing it. It happens when people are chatting away happily and someone (often innocently) interjects which shuts everyone else up and kills the chat.

chatkill 

(usually in an FPS game) When someone kills you while you were writing something in the chat. Very annoying.

You: "chatkill goddamit"
Me: "So fucking what?!"
